+1 on the wabi. Definitely a lighter frame and better steel material than the kilo. I had a classic before I got my custom Matthews. The road-like geo suited me well, but IMHO it did feel a little sluggish. Then again I had a 52cm which has a HA of 72 degrees. If you're looking at a 57cm TT length, the 73.5 degrees HA would decrease the trail, making the bike more responsive.
