Iam a old fixed Broadhead guy from long ago BUT...
I used the tekan II's last yr and the yr beforewith my compound and they were great not like the old version,this yr Iam going with the slick trick with the Vortex and the Tekan's on the Pro Fusion,put the rage on the arrows for the Drenalin and they seem to be ok but if your not carefull and check them out you might run into problems, seems they like to open up a bit when banged around not so true with the G5's...and as far as the Slicks go they are just that on my Vortex......SLICK......
