I agree with most of the post here.Tune your bow correctly and you can shoot either without any problem. I shoot both expandables and fixed and they all hit basically at the same spot. But if you just want a good expandable i have shot the Wasp Jak Hammers and the Gators by Rocky Mtn with good success. Tune your bow and you can shoot most any broadhead.

i'm going to try grim reapers this year...i've heard lots of good things about them

another vote for Grim Reapors....but it does sound like the bow needs tuned....I have a 100 grain Muzzy in my quiver for coyotes...it shoots the same as the GR's
