I rotated between to runners, LS2 (Stock), and Step Steel... Both are profiled to 9' and neutral pitch. I rotate so I always have sharp skates; problem is my LS2 last 2 skates and my Step Steel last 4-5 skates before dulling. Would FBV buy me more time on the LS2 between sharpening, since it appears that the walls supporting the edge seem thicker than a traditional rocker? BTW, I use a 5/8th ROH
