Definitely sold on the FBV sharpening. I haven't noticed the glide as much as the extra bite. Went with the 100/75 and could really rip ruts in the ice with out getting any chattering or slipping. Also, I almost felt more stable on the ice, but it might just be the extra trips to the gym finally catching up. I am around 200# but am using 296mm steel at an 11' radius. I used to always go with the 1/2" hollow because anything smaller and I would catch edges particularly on transitions. I would have to get them sharpened every 4 or 5 skates, so I am hoping to get more from the FBV. They did charge a premium and it was an extra 20 min drive so I don't know if I will stay with it. Speaking as a beer-leaguer, I know a few on my team that would go out of their way for it, but if I posted on the "league" forum a bunch would follow. No use in feeding the competition.
