Anyone use them? I am looking into getting one because my IT band and hamstrings are usually tight as hell. Can't figure out which one to get, found this combo one, but I feel like it is too small, not wide enough.
This one is 13 inches wide

Or I can get either the high density or nobby one that are wider. I really don't wanna buy two, but I figured the combo one gives both and avoids the decision.
Anyone have experience with these? What do you use?
