Heres my 2 cents BDD, think about whats changed since turning master.
1. The tees are longer, what did you do? you purchased the RD9 driver, good choice its got the distance you need and its meter isn't as fast as some of the other drives.
2. The greens are faster, but you already have a Daytona putter so theres no change needed there, you just need to practice.
The fairway hasn't changed so the irons you used as a pro (when you where scoring in the 60s) don't need to be changed right now.
you need to get rid of your hybrid and LW and replace them with two other wedges. Because your Pro Rapture wedge is 110 yrds the rest of the wedge distances should look something like this 98 77 50. Your LW is redundant on the very fast greens i hope you agree.
The example you mentioned above is a computer problem that happens time to time to everyone, it has nothing to do with being a master or your equipment.
My advise to you would be use your RD9 driver as a gauge i.e wants your consistently hitting on or around the ding line, then and only then think about up grading your irons. I personally think the Pro Rapture irons are adequate for your game right now, and the extra distance and back spin that the up graded irons offer is not worth the compromise of a faster meter you cannot control
A lot of players may say look at other masters bags and see what their using, i don't recommend that because every ones meter speed comfort zone is different.
Also you may want to consider buying the new balls on offer in the pro shop , every little bit helps , cheers
My putting is just like my dick.......it stinks
