You've gotten some pretty good advice I think. I would take the advice of the bike store you choose on which frame to get. I think it would be hard for anyone to outside either frame as far as speed goes.well, I know I cant. I'm more comfortable with endurance geometry. I ride the hoods alot unless its windy or I'm getting after it. Ride and enjoy, dont clog your mind with to many numbers. It's easy to obsess over it. I did and still do from time to time. My point is if you keep it fun, you'll ride farther and faster and will look forward to the suffering.
