I apply these on a case by case basis. My last acoustic used some very figured Brazialian rosewood for the sides and back. The grain in the sides was pretty crazy and the side braces kept things in check. No failure in use yet.

The guitar is so full of cross grained construction that it boggles the mind. Try to alleviate one cross grained faux pas and you're sure to introduce another or maybe two! Oddly enough, a careful build seems to allow them all to work with their own inherent deficiancies.

Amazing. I'm putting my picture of Torres back up in the shop. Guarnari needs company.
