Have used the 100. It's the most precise frame I've tried and very comfortable. Only downside is the lack of power and plow. If you're using the Tour you may find yourself leading up the 100 to the point where you're almost back to a Tour. Coming from the Tour you might enjoy the base 200 model more than the 100.
