I would like to see some of the current "glue on" heads (snuffer,tusker,magnus, or even the deadhead) with thicker blades ( like new alaska bowhunting screw ins-.072) and heavier weights.(250 to 300). I have been playing with very heavy wood shafts and to get a decent FOC on a 650 to 700 gr shaft you need to have more weight up front. Currently trying "woodie weights" but with more energy on impact with a heavy arrow I would feel more comfortable with more strength in the blade...couldnt give 2 squats if they were single bevel or not.
