I really hate to post in this quagmire, but I wanted to clarify my post earlier (back on page 1). I don't believe Birdseye is weaker than regular maple, I was just saying that according to my understanding of what causes the Birdseye effect wouldn't actually make the wood stronger.
There is a quote in "Make Your Own Electric Guitar (2nd Edition)" by Melvin Hiscock where he talks about Birdseye. I don't have the exact text but basically he made some comments about the dependability of it. But quickly fallowed that up with information from Warmoth, the long and short of which was that people are likely to use a totally unsuitable piece of wood, just because it has Birdseye on it, thus making a bad neck. The point being that as long as the underlying wood is worthy of being a guitar neck, the Birdseye doesn't make it any better or worse. On the other hand, if its a twisted piece of shit, it doesn't matter how pretty it is.
