The lake I often fish is 70-100ft deep within a cast to the bank.  It gets a thermocline anywhere from 20-25 feet in the summer.  Would a flutter spoon work just keeping above the thermocline and not going to the bottom?

Probably. Definitely worth trying, just keep it above the thermocline of course

Worth a shot, small and big flutter spoons gave me a lot of additional bites/fish the last year and a half as I've been learning it.  This is probably obvious, but they've done best for me when bass seem to be corralling and eating shad in open water and won't come all the way up for topwater.

We do it a lot around here post spawn. They will suspend deep over trees and are easy to see on 2D.

Count the thing down and hop it back. 

 

 

Well, I gave it a shot yesterday and was able to get a few.  One was over 4, so it worked fairly well.  May have to give some of the big spoons a shot, just not sure how easy they are to keep further up.

A lake fork flutter spoon is maybe my favorite livescope lure
