I've stuck with the Slick Tricks for the last three years. I noticed the Newer Tricks for 2006 got burred pretty easily after a pass-thru and that could be from the surgical sharpness and the thinness of the blades at the edge.
For this year I plan on testing the New Titanium Bullet, aSteel Force Broadhead, the Hades by Grim Reaper, The MX-3 Muzzy and the Maniac from Aftershock. G5 have also improved a whole lot.
However you can get loads of really good fixed blades broadheads today.
