Did you find the link in my post to the Wiki??? there is a really nice diagram of edge profiles in that link..

Yeah I think you were right in that post Kelly it might be a touch warped :( Could we also be not seeing a bit of a frown in the center????
So hard to tell in pics what would take 30 seconds in...

Where is the smile????

Look here for some info on edge profiles, everyone sees stuff differently but this will help, in general Smiles are a good thing and Frowns are not sorta like the same way...
