YankeeJim:
I can only speak for the 81 TMs and lower.
Try a sleeve or 2 of the lvl 61 balls if you have adjusted to the 81's meter, I think you will like them (especially approach shots)
and if you like them but still prefer the faster meter, the level 50 has the same stats with the 3.0 meter(slower)
FWIW, I play the lvl 81 on a few of the courses and like it, but it is harder to figure approach shots with the extra .5 spin for some reason...
