Seems like that would be better, yes. Anything that keeps the entry point of the belt as high as you can. There's a nice simplicity to that concept.

In the early design stage of my x-belt mount that rhonal89 linked to, I was thinking of doing something similar as far as having the belt enter high and dip lower where it'd be easier to deal with a tie point clamp. I wasn't sure, however, what if any angular/twisting forces that would create so I kept looking for an idea where the clamp point would be as high as possible. It could be that any of these ideas would work fine with only subtle differences - I just tend to avoid possible concerns where I can.
