thanks for the feedback so far, ladies & gents. it pretty much confirms what i thought...stick with what you know in terms of dual or HT. the only next thing ill have to debate whitin myself is whether it would be 26", 650B or 29"? i love climbing with my current 26" HT, but would like to try the other wheel sizes as well! i am fairly short at 1.78m and maybe i should test the other wheel sizes before making final choice.
