I was checking out the Tekan also. Looks great, and I like that cutting tip, but here's the problem: the way the broadhead must open is with a "cam action" (the front bleeder blade edge is pushed backward/down, which then spreads open the blade tips at the rear) rather than the usual jack-knife action (where the blades open by swinging from facing front to rear). So with this cam action, there would need to be some way to make the blades stay open, thus a spring is used for this I guess. I'm concerned that a little dirt/mud/grime can get into the ferrule where the cam action slides down and you just won't get the bleeder blades opening up. In that event, it would make for a very small wound channel. Time and field experience will tell, but I"ll pass for the first year on this.... and keep an open mind for next year. I'll stick with my old but reliable titanium rocky mountains (since I'm on a roll- one single broadhead has taken six deer so far, with only a change of blades four times. I'll use the same one again next year if possible... as long as it's shooting well).
