Comparing the LibTech TRS and the GNU Rider's Choice I found that I like the RC more because of the softer flex, the asymmetric sidecut and the sintered base. But one thing that made me wonder is the different shapes of the noses and tails. The TRS has the nose and tail bent up a whole lot more compared to the RC. I started to think and I can imagine that a stronger bent up nose and tail only has positive effects. With a higher bent up nose you should have better float in powder and the nose shouldn't dive in so easily, right? And also with a higher bent up nose/tail you should have better stability while doing hard bent nose and tail presses / manuals without falling over.
Can you tell me why the RC doesn't have the nose and tail bent up so much? What is the advantage of this shape? I think this is a major disadvantage, but maybe I'm wrong.
