RE: Arrow penetration vs. weight
That is true Dave, increaded oscillation will increase friction. Not only that, but a 'flimsy' shaft will loose momentum upon impact due to theoscillation of the shaft. That momentum would be much better spent following, or perhaps even driving,the broadhead into the target. Needless to say, the topic of penetration is far from a remedial one!
When I first read the topic of this thread I almost ran, ran screaming into the night!!
