I use a mouth diaphram about 90% of the time. I like the Palate Plates the best- they seem more consistent than others (most brands I seem to find about half of the diaphrams will make good sounds and the rest are either poor or total junk). One little call can do it all. I usually bugle without a tube- at close range it doesn't seem to make much difference and I hate having the tube in the woods.

I also pack either the origial Sceery cow call or a hyper lip single. I keepa Hoochie-mama around just for variety but don't really use it too much while hunting.
