I can somewhat answer my own question...
My first bow was a Browning Stalker (ancient). And the first deer i shot with it was asmall 7 pt (man was i pumped

)...but here's what happened...the arrow didn't pass all the way through, and the blod trail was minimal...although i did retrieve the deer, it was a pretty difficult track....now it is much easier to find game with a new, fasterbow, lighter, shorter arrows, and better broadheads
Maybe that helps you understand what i was getting at...
