2013 Srixon ZStar, ZStar XV, and ZStar SL Golf Ball

[Blynn78]

I have tested a few balls recently (b330-rx, ProV1, and Callaway Hex Blacks), but I have stayed with the Z STar tour yellow. I only have a few sleeves of the prior generation left and just picked up 3 dozen of the new generations (have yet to play them). I hope the new ones are as good as the priors. I just can't find anything better for the money.

For me and others like me, because I need more driver spin.

Hawk, how can I tell if I need more or less driver spin? My comfortable driver swing speed is 90 mph.
