Bit of a sidetrack here...sorry.
Is it just me....or does ziricote look an awful lot like the Madagasscar RW that was available several years back (and I don't seem to see any more)??
John, here is a pic of one of your Mad RW guitars from awhile back;

Reportedly, the back is cocobolo and koa. !!
Can't recall seeing cocobolo look like that. Again, I thought for sure it was either Mad RW or zirocote.
