I'm using nearly the same arrow and bhead. I put a Zwickey Grappler on behind the bhead and the arrow stayed in one turkey and a big test rooster w/ Phoenix, both dropped in their tracks at about 20 yds. I had trouble w/ grappler sliding up onto the vanes in flight, a small rubber o ring solved that problem. Blew thru one at 30 yds w/ Emax and it went another 30 yds and ruined the grappler. Don't know what your vortex will do, these may not keep the arrow in at your fps. I'll take the accuracy I'm getting over larger cutting diameter as I shoot from a rest in a ground blind anyhow. amazingly, the grappler didn't change poi at 30 even though it's 20 gr.
