For long saddle hours, with your aggressive riding habits, I'm sure you'll want the bar a bit below the saddle and be stretched a little. Any problems with hand/wrist pressure can be moderated by double wrapping for better ergonomics, and frequent changing of hand position.

Nothing can beat an aerobar for comfort and pedaling efficiency for long daily rides. Profile Design Airstyke fits the bar with no loss of hand positions.

I agree that a size larger frame than one would use for racing will make a better tourer.
