I have a 7vwh and a 777dy, the 777dy feels smaller, feels awsome. The 7vwh seems to be a little more fat than the 777, but it has a - solid- feel to it. Also I run 10-52's on my guitars, so they feel kind of "tight" on the
string tension. IMO the tone is better with the heavier strings. I havn't had any experinece with the UV's, but am in the market for one now, definateley a wider neck. Looking for a 7PWH.slobber,slobber,slobber. It's all relative to what's comfortable to your hands, if it hurt's, either practice more, or maybe switch to a smaller neck. They're all GOOD!
