My favorite is The Rocky Top Game Calls, Glass. It sounds great. But for those who Don't Live in TN. The "Glass Queen" by Knight&Hale. Sounds pretty good. Super loud too. Good for windy days.

Scott Ashburn slate call is my favorite The one on the right.

i have never made my own... wish I were that talented
I did just pick up the new Knight & Hale White Liar... like it so far...

I just bought a HS strut slate call, the ring zone or what ever it is. Its my first friction call trying to learn. This is my first year turkey hunting.

I def. recommend the freak frictionite, by primos... It is one of the sweetest sounding slate calls I have ever heard... I also have one handmade pot call my uncle made for me, and I have a HS Strut ring zone, a HS Strut Aluminator, and a Primos Slate/Glass combo... I am not any good with a mouth call, so I rely on slates and box calls... I do most of my calling with slates though
