Actually...
My Pista Concepts did climb very well. The really stiff rear triangle never got mushy or bouncy when climbing hills.
That being said, dude if you are going to put risers or something on the bikes, then the geometry is out the window. Also, tight/aggressive geometry doesn't start to feel good until you get well over 30MPH (48kph). Until then, it's twitchy.
Pick the one that looks coolest.
