OriginalSix-- don't know where you are at but I will offer the same as JR if you are in my area (mpls); don't post here much so won't go so far as to extend the shipping part since nobody knows who I am. But after being firmly in the 'disbelief' camp until I had a chance to try it for myself, now I'm not sure how one doesn't feel the difference. One of the funnier things I've seen/heard was from my younger boy, who's skates I've been sharpening for years at an increasingly shallower hollow as he's gotten older (now 13, and was at 5/8" ROH) asked my after the 1st time he skated on the 90/1 fbv, "What did you do to my skates?" -- probably because I didn't tell him beforehand that I changed it out as I wanted to get an honest appraisal of fvb, and I got it :-) He adjusted quickly to the extra speed he carried throughout his transitions and into/out of corners even with that deep of 'fang' on somewhat soft ice.
