Of course, it was a lightweight carbon bike. I am quite a bit slower now on my Trek Pilot (also full carbon) but am also 10 years older. But the Pilot has 700c wheels -- if they are faster than my old 650s, I haven't noticed!
On a touring type bike, I don't think it's going to make much difference; it's not likely to be a speed demon no matter what. Also, I am 5'2" and after checking the geometry, I know there's no way I could ride the 46cm LHT. YMMV, but the 42 cm would have to be the one for me -- and my Trek Pilot is a 47 cm.
Still, it doesn't hurt to check and try. I know a lot of gals my size ride larger-framed bikes, but they don't work for me. My old Terry Isis was a 17.5" frame (equivalent to 44.5 cm, if I remember correctly) and fit me perfectly.
Good luck and keep us posted!
