I have not personally used those Accra iron shafts before but I would say that you have in fact already bought them, then I would give them some time before you make any decisions about alterations. At least 5-10 range sessions and a few rounds with them. If you haven't bought them, I would say that 123g graphite shafts are really heavy and probably not best suited for someone with your speed. They may help with the joints but they aren't going to offer anything to help with speed or distance. I would be looking in the sub 90g range. If you do own them, you would need to change the shafts more than just change swing weights from removing possible tip weights.

2019 Goals Decide on a new home course since moving Play 40 18 hole rounds with at least 15 eligible for handicap entry Work on solid contact with the ball for additional distance Lower my 16.3 handicap index by a stroke   I did join a nearby semi-private club in 2019.  I played about 30 rounds but had 20 eligible for handicap.  I did make decent contact but did not gain much in the way of distance.  And my handicap went down a half point for a while but I ended up at 16.5 .

My wife and daughters take 10 minutes just to get out of the car when we get home! I keep my clubs and shoes in my locker at the course, but once I get to the locker it doesn't take me long to get everything out and situated. That being said I normally get to the golf course with plenty of time to spare so I don't have to rush. I've worked there for 15+ years, I know everyone, and I like to go in and chat, maybe get a cup of coffee, eat breakfast. Talk to the old guys that are always sitting at the "table of wisdom" in the restaurant. I believe in being early and not rushing. 

I have used something like this and it worked for me. I like that I can adjust the tightness/pressure and pinpoint the location. I tried elbow sleeves before but it was either not compressive enough or it restricted my movement.

It takes me less than a minute to set up my Clicgear. 😉 I don't see a correlation. I like to arrive at the course early and lollygag a bit. I start the round more relaxed that way. I hate having to rush from the car straight to the tee, and it drives me crazy when it's 5 minutes before your tee time and your friend is pulling into the parking lot. Different strokes for different folks.
