i started with wizards, then I switched to aviars, but for the way I putt, I ended up going to the pig, and I know everybody laughs at me about it, but I find it's what works with me..I tend to put a lil' anny on my putts so with the pig being overstable and heavier, it helps correct that, plus it's the best thing to putt with in the wind...so those of you that like the rhyno, try a pig and see if you like it, i'm not big on the R-Pro plastic but the pro is great. plus once you beat it in, becomes a great mid range also.
