I like a few of whatever Yek's envelope had in it. I'm also a big fan of HT's Tom bomb, though I've found they take a little while to "warm up." I carry 3 of that model every hunt just in case I drop one. I use a primos heartbreaker for striking birds later in day/morning. That box call has killed a pile of birds for me, I've had it since I was 6 years old. I've never been much of a pot caller, but the ones posted on here look super nice!
