LV,the layout of a diaphragm turkey call still is very much the same as it was in many years past!Dont think just because it has a namebrand on it that it wont make you gag!!For many getting over the gag reflex,or just getting the call to fit properly or comfortbly to your palate is alot of the battle in using a diaphragm call!An improper frame size can make an individual gag and can cause the call not to operate to its full capacity because air will get around the call instead of through your tongue and reeds!A double reed or light triple reed is a good suggestion to start with and for beginners I would suggest a frame like H.S.' s alumistrut line of diaphragms.The frame is bendable and can be made to fit to the contours of your palate making it more comfortable,and more importantly it will stay in one place,which is very important in maintaining a consistent quality sound!Hope this helps you some,and keep practicing.Bob
