Just got a pack each of the screw in and glue on Tree Sharks and have to say they are wicked.They are also the easiest heads to get to spin true Ive ever put on a shaft, didnt have to fiddle with them at all, stuck them on my Cedars and no matter which way I turned them they spun perfect, aluminums the same way, tried 6 different size shafts and they all spun perfect.
I shot broadhead target 4 times in the basement at 10 yds. in the same place and they cut a hole big enough to stick your fist in, could ruin a 3-D target real quick with these, cant wait to try them on a deer, looks like they might replace my 160 gr. Snuffers....
