I switched to Solid Broadheads, just a bomb proof head, my runner up choice were VPAs, both are outstanding.
I was a Muzzy guy for years but they just aren't as good as many out now. I like Magnus Buzzcuts and just bought some VPA heads. May be the best made head around as the are CNC machined from one piece of steel but they are not very sharp and you will have to sharpen them. Fly great however. Magnus has the best warranty around. They will replace any head damaged for any reason. Several good heads out and you can't go wrong with most of them.
For a fixed blade head Slick Trick for me. Flew great with little tuning with my field tips. I shoot mostly mechanical for deer hunting but for elk I opted for Slick Tricks. Heard some good and some bad about the Toxic heads. Never tried them and really don't have a reason to with the broadheads I am currently using I'm satisfied. If it ain't broke don't fix it.
QAD exodus is the best fixed blade broadhead on the market IMO. They fly true and I killed 2 deer in less then 45 yards from my stand last year with them. Oh yeah, and im shooting 40 pounds!
