I’m inclined to agree Mitch, its not so noticeable when your just listening to someone else play the instrument, its the different feel/experience that the timber seems to give to the instrument as you play it yourself. Things such as responsiveness, and the feel you receive back through the tone holes, as well as how easily it reaches the second octave. Boonaree and Arizona Ironwood are my two favourite timbers, both of them sound absolutley gorgeous, but there as different as chalk and cheese (and i’ve made quite a few from each wood), Boonaree’s so crisp and bright and responds like lightening, were as Arizona Ironwood is dark and moody and loves to be pushed around. All this probably amounts to bugger all though 
, but i’ve got admit it keeps me fascinated 
Brad, I’ll take a few pic’s showing the timber lengthways and then you will be able to see some more of the grain detail.
I do have some bigger chunks of the main trunk of the unidentified (as yet) tree, I will take a couple of pic’s of that too.
By the way Paul, sorry for Hijacking your thread, I will start up a fresh one where I can post pics of the timbers for Brad.
Still…some fine looking whistles there mate.
