At the TOC in the 90's, the Torqueroll use to be what seperated the men from the boys. It use to be who could do one, period, that would end up winning. Then it was who could do one better, then who could do one lower, then who could enter one more creatively.
Nowadays, it is still a very important part of their routine, but creative harrier flying is now also needed to have a shot at the title...still, it gives you an idea as to how difficult a TR is.
