I have Primos but I don't use the blue reed, just use a diaphram with the tube. Also, I found another tube (no reed on it) that I use. If I have a bunch of crap in my pack and space is limited I use the Primos pack bugle, again usually with no reed and just a diaphram.
Another vote for the $3 dollar fatty wiggle ball bat and a roll of camo cloth tape. I call it the canyon blaster. It really reaches out and touches them with a mouth call.
