In my uneducated opinion, speed is important to the lower end market where archers seek maximum "bang per buck" in order to maximise the effect of lower draw weights, and tortional stability is important to the higher end market where every point counts and the technique is relatively refined.
If there is a trade off, them perhaps it is indeed two different limbs for different markets. Of course you will still get "low end" archers buying "high end" limbs, but c'est la vie.
As for barebow - is that particular market big enough to worry about in terms of capturing the niche?
Sorry... what was the question again?
