WAHat clubhead speeds are best for the NXT TOUR S, NXT TOUR, PRO V1 and PRO v1x

HOW MANY PLAYERS ARE PLAYING  REGULAR (NOT BELLY) KOMBI PUTTERS AND WHO ARE THEY?

What is the major difference between the MB 710 and 712 irons?.  I have read about the sole grind, but after that they look about the same.

How often do the tour players change balls?

Is Titlest thinking about making an optic Pro V1 and Pro V1*?

What was the thought process in developing next/gen NXT Tour, having received my 2 ball sleeves compliments of Titleist, you have come up with a good product.

If I was to get a new shaft in my putter, Scotty Cameron laguna 2.5, would I be able to get a 38"or 39" shaft that would fit into the club head? Im 6'5" and i was playing with a belly putter(i don't like them) and it really felt comfortable.…

Does Titleist still offer custom sets of MB irons, I'm looking for a set of square toe 712 MB 2-pw. Also do you offer any grind features [ such as more camber]  Thanks, Mark

Do you still notice the different grooves(V vs. old square) in your irons and wedges?

I used to play the Pro V1 ball because I liked the spin around the green but a Titleist rep said that the V1 and V1x have the same spin while I'd get more distance from the Pro V1x.  My driver swing speed is 90; which ball would you recommend?
