Thanks for the heads up Steven. I'm going to give up trying to achieve any "practical spin" while using my WGT starter clubs & unlimited balls. If I understand things correctly (& your comment above), workable spin (especially any degree of backspin on the green) is only achievable by having higher level wedges & balls. The higher level, more expensive equipment, the more spin that can be expected & achieved.
I may have to invest in some top-notch wedges & max spin balls after all. (I've seen balls having as high as a 5.0 spin factor. Luckily, about a year ago I fulfilled some offers that earned me 9,060 credits. Looks as if I'll have to redeem them for some wedges compatible to my Level 91.
As mentioned before, my main goal is wanting my ball to stop dead in it's tracks (or even backspin when needed). when going for the green. It's not real discernible, but in other applications I do think moving the "little dot" in the center of the golf ball to various positions does affect the amount of roll I get (even using my starter clubs). I guess for now I'll have to be happy with that until I buy some quality "pro wedges & balls". Slim
