I think Will has this pegged very concisely. Aside from a Talbott or two that I have packed away somewhere, the only true seven-folds (understood in the usually imprecise way) in my collection are these two made in England for RLPL:
immsmc, these ties are constructed in exactly the same manner as the Talbotts. The silk, however, is stiffer--which leads to the very problems Will outlines. The Talbotts tend to be made of a more fluid silk; they wrinkle less, but they also have a vintage look that can be difficult to wear if you're not out at a forties party. The RLPLs give off more of a 20s/30s vibe, so they don't seem so costumey (to me at least). I think I find myself in agreement with those who admire these ties more as beautiful objects--singular expressions of craftsmanship that needn't be draped around any actual necks. Though they certainly create their own aesthetic, I would be hard-pressed to label the true 7-fold the perfect tie.
And in that spirit, iammatt, I must say the striped Rubinacci is extremely nice.
