I hear ya! I liked the calls that would do all the sounds needed. I had a MAD call, one of the older ones, and I still have it. It would do buck, doe, fawn etc. The problem was that on a cold day, like many calls, it would freeze.
So I'm gonna go with the haydel's inhale call for my buck. It is supposed to not freeze. I carry that, my bleat can, and a rattle bag. These three things fit nicely in my fanny pack and don't take up alot of room. I have a skirt around my treestand, so I can make some movements without being seen.
I hope this advice helps. I'm trying not to be redundant.
You can't kill'em sittin' on the couch!
