Maybe peach can advise here, but aren't Harlicks' the stiffest skates mostly for the very advanced? Two singles aren't going to require that sort of stiffness. I have all of my singles and am working on the axel and I see no need for custom boots. That's really for the more elite level. Different boot brands have different feels, I've always used Riedell and didn't have issues but am thinking about SPTeri's, anyone have an opinion on those?
BTW this is Lanternlight, I picked a new name for the new GS.
