Hey all! So, I’m convinced that I’m in need of new (stiffer) shafts in my irons. This is based on a few data points: 1) I have a two way miss that I am having great difficulty correcting. Either a push straight right, or a hard overdraw/hook. I read that some who have too-flexible/light shafts can have this miss pattern. Seems to fit my situation. If I S L O W my swing down, I can straighten it a bit, but it feels unnatural, like I’m putting the brakes on my swing. I’d rather swing full. I feel like I’m walking on a razor with the ‘right’ speed, and I’m thinking it would help to have something else that I can’t overpower so easily, and so I can commit to each shot. Basically, 2 out of 10 shots go straightish. 4 go left, 4 go right. I do not have a problem with contact anymore. I get it ‘up’ plenty easily, and don’t hit it excessively fat or thin very often these days. (Just a little fat/thin, haha). About 8-10 times or more per round I hear myself say ‘yeah I hit it good, it just went way left/right!’ 2) I’m 6’2 with about an 88mph 6i swing speed. Carry it about 175 or so. Distance is not my problem. Even losing just a bit would be OK if I start hitting it a good deal straighter. 3) I’m playing stock Ping AWT R-flex shafts in my G15’s. These shafts weigh 99g. Pretty light compared to almost any Stiff flex shaft out there. The ball launches high, and I do like that. But if something stiffer would drop the flight a bit, but keep me straighter... I’m interested. When I bought the irons new, my swing was (more) crap, and I couldn’t generate too much clubhead speed. The salesman/fitter said I could go with Stiff graphite shafts, but since the R’s were steel, they would play ‘stiff enough’, anyway. Probably/possibly true back then (2012), definitley not the case now. So... I have tried the online fitting sites from True Temper and KBS, and though I can play with the answers to the questions a bit, I get vaguely consistent results. Normally I’m guided toward KBS Tour S, KBS Tour V (Stiff), KBS C-Taper Lite, or Project X 6.0/5.5’s. The problem is, I have no idea what each of these shafts would really do for me. My number one goal is to significantly straighten my ballflight and tighten my dispersion. Secondly, I would like to keep as much distance as possible. Trajectory is of less importance to me, but medium to high sounds good. Of course the best thing to do would be to go get fitted for shafts. I could answer all my questions in an hour or two. Unfortunately, where I live now, (Japan) there are not any places that I know of to go get fit. Plus the language barrier could be an issue. Does anyone have any specific recommendations or experiences on any of the shafts I mentioned, or any others that you know to be similar, or that may help me achieve my goals? Especially interested if your numbers are similar to mine. Most of the shafts I listed are about 110g in weight. Seems like 10g up won’t throw me off too much. Does that sound reasonable? If I can, I will figure out how to get fit here in Japan, but I am also browsing eBay for shaft sets and have come close to pulling the trigger a couple of times. I just want to avoid any extremely costly mistakes, if possible. Thank you for reading my novel, and I appreciate any feedback. I do have a ‘my swing’ thread if seeing me swing my 6i would be helpful.

Good Morning from Houston. I was supposed to get my Shot Zones mapped this morning but it is now at or below freezing this morning after a cold front blew in so I will be waiting until it warms up a bit. However, I have been thinking A LOT about shot dispersion lately, and was wondering what is normal for different levels of golfers. So what is your shot dispersion (left/right) of your clubs? Are you a fairly consistent percentage throughout your bag (say 10% left or right). Or are you abnormally good or bad with specific clubs in relation to the rest of them (10% with short irons and 25% with driver?). Due to your natural ball flight or stock shot is your dispersion mainly one sided (5% Left, but 15% right because you play a fade?) I am curious as to what types of shot dispersion different handicaps here on TST have. Looking forward to hearing from you all!

If you use a launch monitor light FlightScope or Trackman on the range to figure out your dispersion (Shot Zone), do you go by "carry" or "total"? I would assume total, but I feel like sometimes the total (carry plus roll) is a little bit further than I see what is happening on the course. Or do you go by carry and use your personal experience to estimate the roll? Obviously, the roll depends heavily on course conditions and angle of fairways or greens. Just wondering what your thoughts or procedures are?

Note: Apologize for my english.. Hi all, here is my method to decide where i yould aim in an approach shot based on my shot dispersion to minimize the average score for a hole in the long-term. Let assume we are on a Par 3, 100 Yards long to the middle of the green. To simplify the explanation let´s assume we hit the Sand Wedge always exactly 100 yards all the time so we can focus in 1 dimension only (left/rigth misses). Now im going to describe a hole with easy referencies. Each letter represent 5 yard of the element . References: G green, F Fairway, S Sand, R Rough, W Water, O OB, H Hole. Hole: RRRRR SS GGHGG F RRRRR So the flag is in the middle of the green, we have 10 yards of green left and 10 yards of green to the rigth. In the left there´s a bunker 10 yards width, and after that just rough. In the rigth we have no bunker, just 5 yards of fairway and rough beyond that. The green is 25 yards width. Where do you aim? well this is an easy one, i assume all of you would aim for the center of the green towards the flag. me too! but why ? Well i know that the dispersion of my shots are abount 10%. What´s this? Is how much i can miss a shot either to the left or rigth. So if i have like this shot 100 yards to the green i can either miss rigth or left a maximum of 10 yards (10% of 100 yards). So if i aim for the flag (H leter) and miss 10 yards left or rigth i will still hit the green both ways. Lets say i play this hole 100 times, 20 times i will miss 10 yards rigth, 20 times i will miss 5 yards rigth, 20 will go around the hole, 20 will miss 5 yards left and 20 will mis 10 yards to the left. This is because yo never know where the ball is going to go. You just can know how far you can miss rigth or left in your worst shot and work with it. (this is asumming equal dispersion) Now let´s apply some numbers, let´s use the average scores the pro does from an specific distance and lie. Let´s say that the balls witch lands in the hole area are on average 2,5 yards to the hole, thats 7,5 feet. From that distance a pro average 1,48 putts. The ones 5 Yards away have an average of 15 feet and 1,79 putts. The ones 10 yards away (30 feet) average 1,98 putts. So we have 40 balls landing 30 feet away, 40 balls landing 15 feet away and 20 landing just 7,5 feet around the hole. We sum up each score per ball and divide ir by 100. (20*1,48 + 40*1,79 + 40*1,98)/100 = 1,8. 1,8 is the average score for all the ball shot to that green, let add the approach shot aand our average for that Par 3 is 2,8. (in this 1 dimensional world) What if im 50 yards to the hole ? my dispersion drops now to 5 yards (10% of 50 yards). 33 balls will end 5 yards left from the flag, 34 will end up around the hole and the other 33 will end up 5 yards rigth. Same math as before: (66*1,79+34*1,48)/100 = 1,68. Now our average from that distance is 2,68 shots. What happens if we aim 5 yards left to the flag?? 33 balls will land 10 yards left, 34 will land 5 yards left and 33 will land arround the hole. Same numbers... (33*1,98+34*1,79+33*1,48)/100 = 1,75 ! yes, our average raises from 2,68 to 2,75 with the same green, flag and distance. To make the numbers easier, as we are hitting 33 balls per letter, let just shot one to each one. The formula of the last hole will be like this. (1,98+1,79+1,48)/3 = 1,75 What happens if the flag is 5 yards left to the middle of the green from 100 yards (10 yards dispersion)?? let´s see the hole: Hole: RRRRR SS GHGGG F RRRRR Now where do you aim ??? Some will say they aim for the flag, some will say aim at the middle of the green. Let try hitting towards the flag. We have 1 ball landing near the ping, 1 landing 5 yards rigth, 1 landing 10 yards rigth, 1 landing 5 yards left and 1 landing 10 yards left. All the analised balls landed in the green but this last one landed in the sand. Same method, a pro from 10 yards to the pin and with a lie of sand scores 2,39 shots. let´s make the numbers.. (2,39+1,79+1,48+1,79+1,98)/5 = 1,89 (2,89)--> Witch is higher than the 2,8 score calculated with the flag in the middle of the green. Yes, generally as the flag is farther from the middle of the green the hole get´s harder. Let now hit it to the middle of the green. 1 wil land 5 yards left, 1 near, 1 5 yard rigth, 1 10 yards rigth and 1 15 yards rigth. A pro from 15 yards / 45 feet scores 2,09. Same formula: (1,79+1,48+1,79+1,98+2,09)/5 = 1,83 (2,83). In this case aiming to the middle of the green (2,83) is better than aimning to the flag (2,89). It´s 0,06 shots better per hole, multiply that by 18 and just aiming a little better will reduce 1,08 shots per round in this easy scenario. Away from the numbers, what we do is to try to hit the green with all our balls avoiding shots that in average are harder to score than a ball in the green. In this case we prefer aim a little rigth and accept to putt from 15 yards if we miss rigth and making our worst left miss still hit the green avoiding the sand trap. This is easy math to understand our chances in a hole a where do we should aim for better score in the long term, but I just talk about an easy shot, with a green with just a bunker an plenty of green to be safe with every shoot. (Moreover i´m just appying this approach on 1 dimension (left/right miss), it´s get harder when we analise 2 dimensions (left/rigth and long/short misses combined)) What happens if i hit the same green from 200 yards ? What if the green is thinner?? what if is guarded by Water hazard or OB or both ??? What if the green is huge ? when is better to layup?? where to aim in any other scenario you can imagine ?? Well there´s a lot to talk about if you want to, i´m open for questions or dabate. Abrazo de Gol! (Goal hug)
