Michael's shop is a very short drive away from my home. On a sunny day I can easily walk. There is no doubt in my mind that Michael will build you a wonderful guitar that will sound and look incredible.
RE having "one of the best collections in the world", whether that is true or not is a bit irrelevant. Most successful and established luthiers have plenty enough tone woods to build your dream guitar.
Besides, I'm not "skeptical to the wood" (interesting choice of words), I only pointed out that if I were to treat myself with a Greenfield guitar, I would want nothing but the most primo tone woods all around.
When it comes to rosewood, the most sought after pieces are fully quarter-sawn. There are some exceptions to this rule. Some flat-sawn woods show exceptional figure. Other woods are so rare or expensive that you have to compromise.
There's nothing worse than a piece of plain looking rosewood that is not quarter-sawn. You don't get the looks, you don't get the stability, you don't get the prestige -- nothing. Besides, cocobolo isn't so rare and expensive that you'd have to compromise.
My recommendation would be to ask for a fully quarter-sawn set of cocobolo for your guitar. I estimate 99% of the AGF crowd would agree with me on this.
RE the top, I trust that Michael only uses the best sounding tops he can find.
That said, if you think the top of this guitar looks great, you have nothing to worry about

If you don't like that top, let me know.
