WOOHOO!!!!

I personally love that aero seat tube on the TREKs. So cool looking. For me, a slower rider, I would get one just for that. The coolness factor has it's personal rewards. I really like the traditional Trek geometry. It just looks more like a real mans bike. No offense to gals on here, but the Giants do look like womens bikes.
When I got my semi-compact frame, I was really worried about how much slope there was. Luckily there is much less than a Giant, because if it was worse than it is, I would have returned the frame, and bought something else.

I know it really doesn't matter much perfmance wise, but for me it is just personal taste.
