To piggyback Parnell and PD, this is a very interesting subject, but I think it smacks of that attitude of replacing accuracy with a gimmick.
Gimmicks for fun and entertainment are all fair game, after all, remember how we all got a great kick out of the guy that built the all wood cam-action wheelie bow??? Absolute sheer genius, a hale and hearty finger flown at both sides of the wheel bow debate! Sadly, it didn't perform well at all. If he had he tried to take it into the field to hunt deer, we would have all booed him with well deserved derision.
Nonetheless, poison and arrows have a long history together.
