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?

How often is putter loft/lie checked or altered by tour golfers?  Does the putter bend during normal use i.e. leaning on it while getting ball from the hole or from so much travelling?  Noticed that some players that use a plumber neck are very careful…

What loft on Sand Wedges 54degree and 58 degree do you recommend for using out of thin or herd packed bunkers?

(Any of the Tour Pros) Wondering if you were looking at changing any of the clubs in your bag?  If so, which one(s), what are you looking to switch to, and why?

how do I get fit for the proper, length, loft and lie for belly and long putters?

I'm 72 with an 18 index using titleist DOT balls. Is that the best ball for me ?

Last winter I left my clubs and two dozen new ProV1 balls in my backyard storage building subject to freezing temperatures for four months. What effect does freezing temperatures have on the ProV1 balls?

I have a 910 D2 driver set at C3 with a Aldila RIP 60 Stiff shaft, if I put a Graphite Design G-Series 60 stiff shaft on the club will the C3 setting still work or does this shaft change launch angle and spin rate to where a I should try different settings…

I am currently playing the Pro V1 but am interested in trying the new Titielist Velocity ball - how much difference can I expect between the two balls? Thank you.
