I use HOWARD CITRUS-SHIELD, it's a paste wax designed especially for wood use. In box calls some combos just won't work together, they should, but they don't. Have you tried using a thicker lid in those combos, sometimes that's all it takes? Have you had other calls in those combos play good? Sometimes you just get a bad piece of wood that has no sound quality in it at all in it, I've had a few cedar pieces that I've gotten that way, tight straight grain and dead as can be, one end of the board has great sound the other end sound like cardboard, no visual difference in the board, but sound is completely different.
