I would also like to throw my 2 cents in the ring. I have found that the Primos Power Crystal has an excellent sound for glass call. Experiement with different mouth calls and find one that works for you. Also, I have found a good box call can make all the difference in the world on days that the weather is not so cooperative. (Windy) Don't be afraid to try different calls and with their cost effectiveness, you won't sink a lot of money in the experimentation of these calls.
