+ 1 with the muzzy mx3 (100 grain) (mx3 are a little more compact than the others) they fly just as straight as a field tip on my easton carbon arrows. Took 3 deer last year, all double lunged, all pass threw shots. Great heads. Now I will say... A long shot on a deer may give him notice, these heads hiss while in flight and if your shooting 40-50 yrds they might hear it coming. I never shoot that far so its not a problem. Make sure you snug your tips up with the supplied wrench. Only other thing I dont like is the blade get some surface rust if out in the weather... not a big deal to me tho.
