Unless you have to shoot a crossbow for physical reasons, I would get a good compound instead. There's not much real world difference between the two in most hunting situations. With a little practice, you can shoot an arrow to just about any range you feel comfortable and with a flatter trajectory and more downrange energy than a bolt. The crossbows are also awkward to handle and don't lend themselves as well to carrying around. I have limited experience with crossbows but that's just my take on them, especially for the western big game hunter. Good luck in whatever you decide to do and I hope you crush a monster this fall.
