Yes, and it will cut down on how long it takes to sharpen a goal skate (w/ regards to deep hollows) JR I took the plunge and ordered 3 different FBV spinners. I tried the middle one tonight and wow...skating from the blue line to the red I was able to coast all the way around to wear I started. And in talking to Steve after I noticed another thing My knee (arthritis in it) didn't hurt as usual. Although my back was a little sore. After talking we decided you may have to change the center point of the blade as you feel further back after switching the the FBV (don't ask me why). It was also sore because I had more energy from putting out less effort to run the practice and shot a ton more pucks. I think we have a winner here. "how long does it last"? Well I have to say after an hour and 1/2 it still looked like it had not even been skated on. The whole team is getting there's done now as a trial.
