Currently using a Wasp Hammer SST 100gr. Don't know how it performs on big game yet, but it flies very nice for me......matter of fact, just was shooting one not 3hrs ago and it's hitting right in there with my fld point.
A previous head I really liked out of my old bow and used for a few years, was the brown Cabela's Laser Pro Mag, 125gr. Don't even see those listed at Cabela's this year.
One I tried couple years ago that I did not like was Cabela's Laser Supreme 100gr w/locking collar. The blades on the ones I had were slightly loose after tightening the collar and I never did get them to fly well.
Others I used in the distant past were Bear Razorhead and a Savora like bfisher those mentioned, 2 or 3 Rocky Mtn heads (one at 145gr), and a couple Satellites.........really can't say I miss any of them.
