I'm sure many will chime in here. In my opinion, the TW is a jack-of-all-trades bike. It can do it all, just not fast! I'm 6'5" and weigh 260lbs, just raise the bars and move them forward some and you won't feel bent over on it. How much of your 45 minute commute is over 50mph? Mine can do 60mph with me on it no problem, but it is near it's max RPM. I jump on the HWY for short jaunts but I don't like riding more than a few miles on the HWY on my TW. I have the Seat Concepts seat on mine, I really like it. Check out my TW build thread, much of the stuff on it would be great for a taller rider like you. My favorite thing about the TW is that I'm not afraid to try new trails on it. It gets great traction with the giant back tire and it's small enough to man handle when the going gets tough. I'll ride it many places I wouldn't even attempt on my larger bikes.
