Iron shafts

I currently have nst pro 105t and tend to get a high flight on my irons shots and was looking at changing to a kbs regular tour shaft to try and lower my flight

what are the thoughts

Sorry mate, I have absolutely no idea about the technical aspects of clubs and shafts, but thought I'd reply and perhaps bring this to the attention of someone who knows what they're talking about

But if I could throw my two cents in anyway (please take what I say with a grain of salt - I'm pretty new to golf and am no expert) I would suggest it's less to do with shafts and more to do with technique (but I'm happy for the experts on this forum to prove me wrong).

I'm always tempted to shell out money on new gear to alleviate whatever fault I have in my game, but I have a pretty meagre budget and can't afford to experiment too much.

I know this doesn't directly answer your question about shafts. Let's hope someone who knows what they're talking about can provide a decent answer for you.

If you are 5'9" or taller you have steeper angle of attack to the ball and subsequently will get a higher ball trajectory.

I've been very happy with PX shafts myself.

My thoughts are you should get new irons instead. That is going to be a bunch of money. Those KBS shafts are around 25 bucks a piece and by the time you get grips and everything you will have 300 in the change and pullout shafts aren't worth that much. But in terms of ball flight, yeah it would go down with a heavier shaft. You could go to the TT DG300s for half the price and probably get the same feel and flight. I'm just not a big fan of changing shafts in the irons. I would just sell the ones you got and go get fitted for new irons with the shafts you want.

if your on the swing plane your not going to be steeper angle of attack unless your casting the club if you want shafts go with project X 5.5 or 6.0 and have them fitted to you> meaning get a club fitting to find the propper shaft and lie angle mine had to be extended 1.5 in and reset to stanard lie

Changing shafts will cost you a ton, reason why I bought a used set with the shafts that I wanted to test out.

Pretty much most of the stuff I've read suggests that taller ppl will have a higher trajectory and it was thought that it was b/c of a steeper angle of attack on the ball. I know I have a higher trajectory than most and I'm 6'3" and I don't cast.

I couldn't agree more about getting fitted, especially for lie angle. I've done the Mizuno shaft optimizer and none of the read outd suggested PX shafts for me. However that is just a good place to start and isn't written in stone. I pretty much go by feel and of all the shafts I've tried I like the feel of PX non flighted 5.5 the best and get good distances with them, so thats what I currently play. I do most of the work on my clubs myself, so changing out iron shafts isn't that big of a deal to me and I do tinker a lot.

after ten years of working as a clubmaker/fitter i can only say that taller people don't have steeper swings than short people. getting fitted for the proper overall flex of shaft is as important as having the lofts and lies adjusted to fit YOUR swing. most of the major club companies that mass produce sets aren't real concerned with making sure the clubs fit YOU, just that they're somewhere within their predetermined specs. i can take an R flex shaft and turn it into an S that will hit lower ball flights just by measuring and trimming the tip flex. the next time any of you "buy" clubs from a retail store ask them how they "know" the flex of the shafts in the clubs they're selling. i know because i test each and every shaft. any accredited clubmaker/fitter can. retailers can't and don't because it's not cost effective. while you're at it have them FLO your shafts.

You certainly have much more experience than I, so I stand corrected. I completely agree with what you posted about OEM's.

Ive just been custom fit for some new ap2's, i've always struggled with low ball flight, with my new irons i have the KBS Tour stiff shaft and i am getting a much higher ball flight! I wanted the project x shafts but my fitter said that in his opinion the KBS was a better more consistant shaft and having tested them myself on a launch monitor the results were there to see so i went with the KBS shaft and im not disapointed, they also give excellent feel! I don't think it will keep your ball flight down though!

i'd also like to share something with all of you that i read about- back in the '70s ("old skool" dayz for many of you/us!) a study was done on the affect that the length of clubs has on distance. long story short is that length was NOT as much a determining factor as swingspeed and loft are. having the proper loft of an iron for a given swingspeed achieved the desired distance. that is to say that when a club is built to suit the correct "feel"/balance/MOI (and NOT "swingweight") for a golfer then an iron "set" that are all the same length and 4* difference between each will achieve the desired distances and distance differences between clubs. look up "1 iron" and you'll see what i mean. they're the only company doing it. why? because you can't MASS produce clubs this way and sell them retail economically. it's far easier to mass produce a "standard" (and what IS the "standard", who sets the "standard", and where can i find where the "standard" is written?) set of clubs for the mass consumer.
so here is your experiment- before you go out and buy anything more ddecide which club in your bag of irons is the club you are most comfortable swinging and have the most confidence with (80% of the time it's your "go to" club). for most of us it's around the 6,7,8 iron. now take the head off your 3 or 4 iron that you struggle with and cut 1" off the tip then reglue it into the head. i realize the lie angle change and all that but for now try it out on the range. take some lead tape or lead fishing weights and tape with yopu so you can adjust the balance. note the ball flight and distance. the trajectory should be noticeably lower. if not then cut another 1/2" off the tip and try again. do this as long as the length of the club is the same or longer than your "goto club".
you could also take the shaft out of your 5 iron and put it in the 3 iron. the fact that the 3 iron is lighter will cause the shaft to flex lex in the tip and therefor keep the ball flight lower.
now breath...

im only 5'5 and i can get the ball really high

compare the swing arc to the arc of two circles. a circle whose center is 5 feet from the outer edge has a flatter arc than a circle whose center is 4 feet from the outer edge (steeper angle). which rule of physics are you going to break to cause a steeper angle with a taller circle? a "proper" swing from a tall person will create a lower attack angle. taller people MAY have higher trajectories due to their swing arc creating more speed. i've fitted numerous "tall" (6'+) players who hit low ball flights. i would NEVER build a full set of clubs with ANY shafts without getting an idea of what works with ONE club first.
just my $.02

Cavanagh,

Get on the launch monitor and see what you shot shape is. Tweaky has you on the right track here. Also, check out these sites for shaft specs: http://www.nipponshaft.com/steel.html http://www.kbsshafts.com/ Note that the Nippon site doesn't show your exact* shaft, and that KBS thinks "beyond kickpoint." And, do the math. New irons* factory-fit with your ideal shafts may be better than a reshaft.
