Are grey lenses less susceptible to peeling of lamination or polarization off glasses than green or blue? Are grey lenses more durable?

There isn't anything to peel on quality optics.  

And to answer a question from above, the CDM amber lens is a great all-purpose lens.  Even on the brightest days the lens does a great job of blocking light transmission.  

Costa's w/ 580 lenses.  They really make a big difference.  They really make colors stand out.  They make all colors brighter. For instance, I was doing yard work in the spring and i was raking up the dead grass then the sun came out and I put on the glasses.  After that all the brown spots really stood out.

Are Oakleys straight jacket and monster dog lenses made from plastic or glass? Is Oakley or Costa del Mar more scratch resistant?

I may be wrong, but I think all Oakley lenses are polycarbonate.  

If scratch resistance is what you're looking for, look no further than the CDM glass lens (either the 400 or the 580).  When I bought my CDM's, the salesman pulled a pair out of the case and ran a key across the lens.  No scratches.

That attribute was what put me over the top.

I'll probably get slapped for this but I used to have some costa del mar wave killers. Great sunglasses but It bothered me that they'd fog up constantly.

 I have the wave killers too and have had the same problem!  The Army issues us this stuff called op-drops for our oakleys though, and that fixed them up.
