Don't get me wrong...long before woodhaven came about I was using all of CODY's friction calls. Shoot, I'm still using CODY's glass call. I've had this call since I was 12 years old. It's one of the best calls I've ever used, but its running out of glass. I have a couple of wearing spots on this call because of constant use. What causes the overall differences in sounds produced by a slate, glass, or crystal is the striker. I can almost take any call that is placed in front of me and fine tune it and find a striker that goes perfectly with call and make some amazing sounds with it. Most of the time the striker that comes with the call is a standard for a master call that was produced in previous years and they pretty much stay with same protocal. If you get a hold of some quality strikers try running them on your slate, glass, or crystal. I have more strikers than I need, but I can produce any sound you ask me too on any glass, slate, or crystal call. Popular strikers these days are the one with flare tips. It makes calling a heck of a lot easier. Also, make sure you condition your strikers as well. Hope this helps and GOOD luck to all!
