I recommend shaft extensions.
In all seriousness if you like those irons I would leave them alone for now and work on your swing using the 7 and 6 iron. If you are using newer irons then the 6 & 7 are very good practice irons. It might be trying a different shaft later will give you more help with those longer irons. But from a swing development perspective I wouldn't recommend using clubs altered in that fashion.
I know the process of application should be spread out over the next few months but just watching the few already posted makes it hard to wait to see the rest.
Love it!! I am glad I have a bit more time to do mine though.
I love how the question "Why do you deserve to be on the team" is stumping everyone a bit. Have to say appreciate the honesty of all three so far. Hard to blow your own trumpet AND maintain a modicum of humility at the same time ...
Welcome @Largobuc. I'm an ex-Floridian (St. Pete) and started the game at around 50 as well (don't know about you, but I kick myself for not learning this game as a kid).
Lots of good information and conversation here.
