be careful with mechanical style broadheads, I believe it was the rage this last season was found to be malfunctioning for other hunters that were using them this last season. bucks where hit solid but did not go down, due to it not fully expanding. it's a sad state of affairs when tracking deer that do not go down after a 100 yards. one buck killed by someone I know had a partial broken arrow stuck in its shoulder. several does did not go down because of the same reason. lost because it did not die. only wounded.
My opinion stick with conventional broadheads
