It's probably best I do not answer this one... I love Osage... does that shock anyone

One thing I've noticed with whoever you talk to, don't knock the Poplar calls. Poplar/Cherry and Poplar/Walnut are hard to beat. In fact, I think Poplar as a box makes as fine of a call as many others out there. I have a many of calls with Poplar.
Here are a few of my favorite paddles and boxes.
Paddles:
Bloodwood
Osage
Walnut
Ebony
Boxes:
Walnut
Osage
Poplar
Alaskan Yellow Cedar
Bird last year I shot with an Osage/Bloodwood call. Year before was an all walnut caller. All walnut is a deadly deadly combination!
I feel like I'm leaving a combo out and disgracing it... so many to choose from

This is my opinion only and I doubt very many people like my sound from a box call! Loud and Proud!
