Another head I recommend is the Magnus Stinger 4 blade. Wow. Fly as good or better then my fieldpoints and cut like a hot knife through butter. I use them over the SteelForce heads because I can shoot them right up to opening day and just replace the blades and head out to hunt..........oh yea. Both heads come freaky sharp from the box and Magnus has a lifetime guarentee.
What more could you want , I think Ill be shooting these next year along with my vortex's , on the windy days .
