One more to take a look at is the Magnus 100 Grain Stinger (4 Blade), thois is a fixed cut on impact style head with 2 bleeder blades. I also shoot a pretty fast setup, but use 300 CE at 27.5" . Just bought a package of 3 on the Magnus heads and they fly on a frozen rope to the target. I had been using Muzzy 3 blades prior but the Magnus out pentrated and was much sharper out of the package (also a snap to resharpen post practice session and ready for the field) The blades seem very beefy/durable on the Magnus Stinger and the head comes with a lifetime warranty. Replacement blades and bleeders are also available if you choose to replace vs. sharpen.

Just throw more fuel on you fire.
