Whitetail ribs are not an obstackle to any well tuned bow and arrow combination. They're no problem to a recurve or long bow either with the right broadhead. It's a plus if you can slipbetween them simply because it makes less of a smack which I think sends the deer a little faster and further. If you are lucky enough to slip between them going in and out the deer just hear a noise and usually only take a couple hops before stopping to see what the racket was...... and then they fall over. Bust a rib and they always seem to run as far as they can before they smack into a tree or something and fall. But if you're in the ribs and out the ribs they aren't going far 99 out of a 100 times.
