RE: Diaphram call help.
Tongue and air pressure are a big part of the equation but so is fit if you find yourself gaging or it slipping then trim the sucker. Personally I like the Palate calls the best, theywere just easier to get the hang of and when the moment of truth arrives they haven't let me down. I suggest trying the Ivory Palate (single) &/or the Imeprial Palate (double) by primos both are good calls. They will both work for bull talk as well, the imperial you can get nasty with where the ivory is more immature. I like the fact I can throw in the imperialtorun and gun without changing between calls. I still use blow and squeeze calls to create the illusion of a herd talking, flexibility is a great thing IMHO when hunting elk.
