That's a great question. Last one I wrapped that way grabbed too much and wanted to lock up the wheel, so I had to turn it around and it was much more progressive than aggressive. But I can turn it around if it's too weak. Wouldn't mind hearing from other members how they do theirs. I think it depends on how much of a mechanical advantage the drive ratios provide along with braking surface area, weight, speed and traction. Plus some more factors I don't even know about. It could all be scientifically calculated, but not by me. Besides, I like experimenting.
