I found a LHS that uses the CAG One for doing profiles. Searching here and online gave some info but not as much as I'd thought. I know the shop will recommend something to me but I'd like to have an idea from experienced users of it what is a good idea vs. bad idea. My skates are size 8, 272 runner Fusion steel. Will probably switch to some LS4 once more readily available and the breakage issue is resolved. I saw on the Cag site 4 suggestions for my skate size: 25-40 FWD, 30-40 Leaning FWD
