One wrinkle is the the LHT has a somewhat longer top tube than the others for a given frame size. For many women, this will make it difficult to fit the bike -- many women have shorter torsos and longer legs than men of the same height. If at all possible, I suggest looking far and wide to find stocked bikes in early spring. Test ride a few -- at least 3-5 miles -- and see which one feels better to you. If you have to buy "blind," make sure you've got a great bike shop with a good fitter. You may have to go a size smaller than ideal, and make up the smaller frame with a different, non-stock stem. That's where the great shop will work with you; the young whipper-snapper racer wannabes will push you to the bike they want, and the race fit they like, which don't work for most (not all) tourists.
