I've seen all sorts of big stuff, most of which I've forgotten. However today when getting some things they had a 20" (+/-2") Silver Aro with NO DE but the barbels were worn down for something like $140. If I was in the market I would have picked it up in a second though, it was nice for a Silver. I know he took it in on trade, the tail was also a little worn but it would heal right up it was likely just from being caught and moved.
This store used to house a huge 20" + SW Grouper for years, it finally sold though. It was a stunning fish, not common to see huge SW fish.
