MrFunnyWobbl: If you don't mind me asking Jay (not to derail the thread though) why the low level cally balls? So little spin?
For me, it's just the right combination. Even the 33 Cally with the added spin is too much for me. The 34 and 35 are more controllable for me when using full backspin. I've used the Nike 61's quite a bit (closest ball to what I have) and it's a few yards longer (3-5) off the tee, but shorter on approaches when using same amt of spin I'd use on the Cally 34. That added spin takes distance away. I can use them, but I have to keep in mind that whatever spin I would use with the Cally, I must come up a pixel using the Nike to get same results.
Basically, I've got them mapped out really good for all shots and all spin.
Chambers Bay is a little tough using the Cally.
I doubt they'd do much good with lower level irons, though. From the R11's thru what I have now, they're perfect for me.
