C.) BowTech
Honestly, I can't remember if the Xtec was one of the Hoyts that I've shot, but I haven't liked the draw cycle on any of them, so I'd go with the Switchback. Shot one of them a few times and I like it almost as much as my BowTech.
I'm sure if you're having a tough time deciding that you can't really go wrong either way, though. Good luck to you.
