From the BowTech's you've chose ,if your looking for speed then the Allegiance should be your choice it's the faster of the 2 BT's you've chose .

But as far as smooth I'd have to go with the Hoyt Xtec ,even though I'll never trade my BowTech Patriot Dually in for one since I'm partial to BowTech ,I was close to buying the Hoyt because of this bow being so smooth to draw and shoot ,but I too was looking for speed and this is why i went with the BowTech and I'm glad I did. Good luck with your choice because any one of these bow's you choose are all great bow's .
