Cari loves the tripe sticks but they do have the disadvantage of being really stinky (she doesn't think of it as a disadvantage though!). I think they are more digestible than the rawhide sticks and not as fatty, but they don't last quite as long either. I stopped giving her the rawhide knots too, for the same reason as elaine.e, but she's more than happy with the rawhide cigars.
