After the knowledgeable description of tube weights of standard round vs. aero, I find the aero option increasingly less attractive. Although the look with Shimano AX is without a doubt my favorite, I find the weight penalty too costly. Still it would be nice to have one just for display, but if it means not dropping one of my friday morning bike buddies on a hill, than I'll just stick with Columbus and Reynolds plane jane round.
