Well that is an interesting question....The basic answer is yes. As far as a brand and such, that is a personal question as to your mouth size. Since the call fits into the palate of the mouth and seals, you need on that can do that. Also the more reeds on the call the more work you need to do.
I actually did a blog on mouth calls last week

I have always been a fan of Primos and HS calls...feel they are the best commercially produced products, but Quaker Boy has a call that is the foam fit line and they sound good and fit tight. PM me if you need some more help.
