As for your question on certain wood types from a call maker , most have tried umpteen dozen of combinations and know what will work and what won't . And I have 100 % confidence in a reputable call maker not sending out a call that he doesn't like the sound of anyway . The people I deal with won't send me An X over Y box call just because I want one , if it doesn't run to their liking it doesn't leave their shop and they always have the final say .
