I finally got around to trying out the FBV. The Hockey Shop did my skates at 100/50 and I regularly skate on a 1/2 inch hollow. The glide of the FBV is noticeable but not extremely significant IMO. To articulate it more clearly, the glide felt very similar to a regular 5/8 hollow but definitely not as much as a 1" hollow. During my skate, I felt that I had adequate grip on inside edges but not enough for my outside edges. Overall, I just feel more comfortable with my regular hollow and would prefer to stick with it than converting over to FBV.
