With timber with a grain like this, why would you buy a tropical wood.
I, in fact have never bought tropical wood , not an ethical thing it's just that there is so much fabulous wood available locally for very little ( firewood ) if an effort is made , often the most knotty . ugly, half rotten lump can provide the best results , The Ash above had fallen through a farmers fence some time ago and he could only cut off the branches himself as he only had a small saw ,and when I was working very close by he asked if I could cut it for him as he wanted to re-establish the fence line . It was VERY muddy though !!
