If you could kill animals with it 12 years ago, they haven't evolved that much since then so unless you really want to shell out some cash for a new bow, just tune up the old and get after it. You'll find lots of gadget freaks on this site that don't believe a deer can be killed with any less than the latest and greatest. Good luck.
I'll see what the various shops quotes me - if it is significant, I'll probably go the new bow route, otherwise, probably stick with what I have.
