Even the OP's screen name screams Troll, but that doesn't mean I can resist the bait.

The three bikes I've purchased since I started riding three years ago, were, in order: Aluminnum, Custom Steel, and off the shelf CF. The aluminum was very harsh, and I can't think of a reason to buy aluminum these days. The steel is a sweet ride, but heavy, slow handling and with some lateral flex. The CF is a stiff racing bike, but still rides smooth, and it's responsive in all regards. It's a bit noisier, due mostly to what I believe is cable slapping over bumps that I've never taken the time to sort out. I just broke the frame, but I don't blame the material when the bike fell off my car at high speed. I'm surprised there is only one crack (top tube). My CF crank took a major hit, but only has cosmetic damage, and apparently the power meter embedded in it is okay. I'll know for sure later today.

The only people who argue that frame weight doesn't matter are those riding heavy bikes.

CF > Steel > Aluminum
