I really like the A-frame primos and the Sonic dome makes a good sound but it is a little bit harder to work with. River valley outdoes both of those though with the sweet talker and the triple split. I use them now until they break because iw alk around the house with them in my mouth way to much and the plastic come off. (I have ruined three primos call this year, but havent ruined any River Valley's yet.)
