Thanks, I already new all this stuff when we got the Da Vinci. I had done the research and my point was like you said your self above most can't even tell the difference. A lot of folks like the coasting and wider gear ratios and many like you that all are into the weight thing don't. So I say people should by what they like and go ride and have a great time. Do the research try the tandems out and go ride the one you like.

Take Care,
Bill G
