Wood ID please! This stuff is like iron!

Broke a wedge on some sugar maple earlier this year, door yard and fence row trees defiantly seen harder than their forest cousins. Cherry can be some seriously tough stuff. Now a question for the more serious wood guys "wild" or "black" which is prefered and is there and actual difference?

i'll be dipped - i think you're right! not the first time i've made that mistake.

and....i've had rounds of tulip that were a be-otch to split.
