Nice, Clyde. Concise.
The fluffy splotchy spots I see look more like hits than particles to me.
Not sure what sort of crackle you mean if you don't mean the fluffy spots ...... Have you the section on damage at Marblealan's site? http://www.marblealan.com/FAQ.htm
Whooops. The pix didn't load for me. Darn. The vocabulary might help you still but the pix sure would have been nice. Oh hey, I clicked on a couple of the missing pix spots and I was sent to the Wayback machine. You might still be able to see pix.
