kalied, those are the palythoas that were discussed in a recent thread that a lot of people got frm steve when he got out of the hobby recently.
crumbletop, that's the ORA chip's acro I got from fishdoc a year or so ago...I think that's the one you're referring to anyways...as for the favia, you're probably noticing the leptastreas and the 3 types of acans (echinata, subechinata, lord).
yes, the wave front was a cool idea on the front end. It's not anymore difficult to clean (scrape coralline), but it gives a greater distortion on images than it does with the naked eye...
