Yeah, definitely. They'd be suprized if they did several basic tests, like that one you proposeand likeseeing what their long range trajectory would be like with an arrow that's 30% heavier than what they normally use. But they think they already know everything, so they won't do it.
edit.... I'm not being critical of our wheelie bow brethren. It's just that I've played these games with them before and this is the cynicism that results from long experience. [8D]
