Fran, what are you basing all this on? Surely not a physics book. Maybe you canteach us something about it? I don't know about mythbusters, but it surely is relavant in your case of striking at 369fps compared to over half that. Especially when showing clearly, your momentum is much lower than say my recurve setup or dave's ally.

Hey, I wouldn't have brought this up, but one poster posted some BS from HC about a 600gr arrow, and you brought it up with some youtube video thats geared to sell stuff. You might care less, just sharing some info.

There is only one poster that made some sort of sense out of all this, and made a case about stalking and using one pin in open terrain out to 35yards.
