Hey there - I've got sources for all of the woods you mentioned, RHD - and finished pairs of bones, too. But I'll definitely keep this in mind; many thanks for the offer!
I really do want to try lenke - the "whacking" comes from the bones' tendency to rebound against each other rather from force used by the player. There's a lot of subtle wrist/arm movement required to get that to happen, but I can guarantee you that it's not the same as hitting a krin (for example) with a stick. If it were, I think many of the woods that are used for this stuff might break or dent or whatever... (I've got a lovely pair of *pine* bones that haven't got a scratch or dent on them, let alone "creases" from a fingernail or thumbnail.)
The thing is, all woods produce different tonalities (duh!), so... I want to try some of the djembe woods and see what they sound like in this context. (I love the sound of cocobolo, but am - so far - most partial to the wood used in the pair of bones in the link above - much lower and "darker"-sounding.) Am also playing around with using small, lightweight pieces of leather to "mute" the overtones and the loudness - allows for more possibilities.
But hey - some W. African goat rib bones (cleaned up and dried) would be nice, too!
