To start with, as a Master I'd pay 65 crs per sleeve => Tour-SDs :)
And yes, it's a big step in the game, the other being the step to Legend. Difference is, a TM knows quite well what is coming up, a TP may be unaware.
Truth is, approaches become longer and less precise, which makes putting difficult.
Truth is, too, that putting itself remains unchanged - it's still the same very fast greens (sorry, YJ), but - from longer distances usually.
I agree that the game is becoming far more difficult at that point, I do state that this bears the necessity of custom clubs - pling, pling, $$ in their pockets!
Alas, the fun is the same, no, a different type of good!
