I have an ivory Turpin style snakewood by Brian Mero
An ivory cocobolo by Brian Mero
And a derlin rosewood by pappy
I'd like to trade the cocobolo mero (which IMO sounds the best) and the pappy for a buice, mkw, McLain, ralph permar and other makers of this caliber.
I really would like to keep the snakewood Turpin but if the right call came along or any of the makers I mentioned had a snakewood I'd let it go.
These calls all have a straight mouth piece
