RE: Why shoot a xbow over compound?
It's not really an either or proposition. I shoot compound bow (Pope and Young member, though a little disgruntled with their selfish anti-hunter/anti-crossbow attitude at the moment) and crossbow.
There really is little difference, especially with all the 80% let-off compound bows that do away with a lot of the movement of drawing, since they can be held so long at full draw ([eg.] my dad and I timed a woman who drew to early, hold her compound for 4 min 11 sec before shooting an antelope). I shoot a compound with only 60% let-off and if I hunt from a blind-which I've only done once-I think it's more manuverable than a crossbow. From a tree stand, again, 80% let-off compound bow vs. crossbow: no difference.
Crossbows are just plain fun to shoot. I don't think I've enjoyed anything (and I shot handguns competitively) as much as I enjoy hunting and shooting crossbows. It' a hobby I will carry long into my old age.
