Good luck with your call choice, Cat.
Ive never done any resonance testing but Id have to assume that seriously hard woods like Osage are going to sound sharper, and resonate clearer than softer woods. Certainly makes a difference on box calls.
Alot can be accomplished with holding the calls with your fingers in different manners. Just on the rim, or all the way on the meaty part of the sides, different numbers of fingers will change the sound.
Slate being the most pourous of the call surfaces is why early morning dampness or all day humidity make it harder to play or get you notes to break or pop, until it can dry a little; couple that with a soft wood striker and you may have a frustrating time, always carry multiple strikers to combat this.
Well, good hunting, suit up, and help control the dinosaur population. Theyd eat you in a heartbeat...if they could. Yay Chicxulub.!
