Go for it! It is a wonderful journey that makes my golf game more interesting IMO..
I took the dive some 33 years ago. I was an inexperienced golf coach and a fellow coach was an accomplished builder. He got me started. I built four sets of clubs for my fledgling girls golf team. I have not stopped since.
I started with Dynacraft and golfsmith. I had a set of GS Tour cavity Berryllium copper as my first set. I came to GW when GS tanked it in late 1990's and early 2000. I have been with them since. They just keep getting better IMO. I have played or built nearly every iron set they have made in the past 24 years. Nothing is more satisfying that building a set and putting them in play. So much so, that I cannot seem to keep the same set for more than two years.. The bug to try the new stuff is a form of addiction!!
I now have TS-3 and TS-1IM. My next build will be TS-4 in Rapport Core Blue. I don't need them.. I WANT them.
Best of luck to you.
