I dont make calls to be honest. That being said, Ive bought, traded, and played a ton of calls over the years and have developed personal preferences much like anyone else.
Blasted glass and aluminum are the only blasted surfaces ive ever put a striker to and to be blunt no matter who the maker was, the blasted surface just plain sucked compared to a plain surface that had been conditioned with sandpaper, stone, scotchbrite, etc.
If i were a call maker or having someone make me a call, I wouldn't spend my money on frying pan or blasted surfaces.
