Glass could be difficult to learn on, not trying to tell you to get something else but there are easier ones to run. Knight and hale makes a slatek surface thats a great beginner call. Its yellow in color and used to be called ol yeller. One you get it down pat, get a glass or whatever you want. Cheap calls that I killed alot of turkeys with. Very trippy type surface with less squeaks and slips. Not critical to keep it sanded at all.
