Oh, you're talking about one specific model. Highback heights are pretty standard across most manufacturers and models these days. You won't find an entire category of "lowbacks" from which to choose. The Burton Lo-Back is (was?) a deliberate recycling of an old-fashioned design; I wouldn't buy it for any type of riding unless you already know exactly how it will behave for you, or you don't mind pure experimentation and possibly wasting your money.
