I'm considering changing from vise power lift grips to the power oval or just oval grips, and my question is: Did anyone who did this have to drop a size or two, or did you keep the same size? Right now I use a size 4 / size 2 combo, and fits fine left to right, but would I potentially drop to a 3.5 / 1.5? I ask here because getting to my pro shop these days pretty much requires asking for time off from work.
