I'll second Trysler Grounds too. It's on my list of spots I want to hit.
I'll work hard on some sites out there this Year. The problem with the Trysler Grounds is it's deep (120+) with no relief to speak of.
I have heard that there is some structure that has been put out there, I'll try to get some #'s and will keep ya'll posted on this site.
Also it would be a must to be a advanced diver with deep experience.
