I had a 155 Jett. I'd demoed a 143 and it really did not work for me. The 155 Jett was close - I put almost 4500 miles on it - but the TGF is better.

My old 155 Lithia is on my commuter and does just fine in the more upright position. I'm between 125 and 130 and the TGF is great, but I can tell if it were even a little narrower, it would be a problem.
