Has anyone applied spider rigging or trolling techniques for locating and catching "offshore" bluegill/bream?

I've always loved panfishing but haven't had the best luck locating them aside from obvious shoreline structure and vegetation.

Now, I do have side scan on my boat now, so it shouldn't be so tough to find them bedding this spring but I've picked off a few here and there out in the middle of the lake and I know they're probably not alone, and it made me consider adding a smaller jig or something in hopes of finding some good ones.

Am I crazy?
