To add a further slant to the OP.
Is your choice of ball primarily influenced through peformance or price?
Performance, price doesn't really bother me (within reason).
Last summer I started using the old Penta TP which is by far my personal favourite. Typically they now make a new one but stocked up on a load to see me through next summer.
Don't really like ProV's, never seem to play well with them so probably a mental thing. B330-S, Z Star and FG Tour are all very good balls I've no problem using. Want to give the FG Tour X a try next year.
Winter golf I use pretty much anything I can find.
