Recently bought some of these and wanted to recommend them as I've been suitably impressed
Odi ruffian lock-on - very thin with no annoying ridges or flanges, suitably grippy design and rubber compound, zero flex/squish, don't move when tightened down, just what I want from grips.

they're grips, they do what they say on the tin, what more do you want
edit: wow, I take some pretty poor photo's
