I use tube calls that I make myself out of a film cannister and condoms. I carry all the calls you list and then some (drummer, gobblers, wing-beater, push-pull, etc) - maybe 30+ calls or so. But the tube call is a bread and butter call for me -I can yelp loud or soft as the situation demands, throw sounds off to the side or behind, and do a reasonable cluck on it. It is easy to inject intonation into the tube call (shyness, aggressiveness, or neutrality). But the KEY is that the birds in some of the areas I hunt have already been educated on box calls, mouth calls, and slates before the season even starts - they haven't heard my tube call yet...
However, once a bird is interested in me, I do switch over to my slate or Penn's Woods Lucky Clucker to finish him off... Also, the mouth call is always in there, if I need to gobble, yelp, purr, kee-kee, or just sound like a different bird...
