WAS TOLD THAT THE MOVEABLE BAR ON THE RAZOR ACTUALLY HAS YOU TOO CLOSE TO THE SEAT WHILE CLIMBING, FORCING YOUR KNEES TO STRIKE THE SEAT AND POSSIBLY THE TREE WHILE GOING UP OR COMING DOWN. I HAVE NOT TRIED IT OUT FOR MYSELF,THOUGH.
BY THE WAY, I LOVE SUMMIT STANDS AND ENJOY USING BOTH THE VIPER AND THE COBRA
