I shoot 3 heads as well, Rcky mtn snypers, magnus stingers and muzzy's. But i only carry the snypers and stingers in the woods. My reasoning... I like the advantages that each type has, be it fixed or mechs. I also use fixed for larger game IE bear, elk, etc. But prefer mechs for deer. Killed succesfully w/ both. Had some failures w/ old mechs, (too large a cut dia) but the new design i shoot seems to be really effective and failsafe.

Copper, so you know, If your bow is properly tuned the heads should all shoot the same. I jsut tested last week and got a 3 inch group w/ 6 arrows (2 of each head) at 35 yrds. So for me its just whatever i feel like shooting. I prefer the stingers overthe muzzy's cause i think they have slightly better flight and are sharper.
