I like the 2 reed for kee-kee's.I like 3 reed for raspy yelps,and pretty much anything else.The guys have given you some great advice.There are so many options with diaphrams.You really are going to have to waste alot of money just to find one that will sound good to you,fit you,and that you can work.When you do find one itcan bea very deadly weapon!Friction calls,sound great,but IMHO diaphrams have the most realistic sound to them.I would not like to buy pre-tested diaphrams.However I have several if you would like to try them.J/K!
