I've spent part of 4 trips maybe 12 hours total fishing for roaming open water bass, and bass around bait balls with not one catch, only a few hits. I've caught several I've seen moving around along the bottom while conventional fishing, and a couple of roamers while conventional fishing. But as far as specifically targeting open water fish, even at Dale Hollow, where that pattern excels, NADA.
I see nothing easy about it. Wind blowing you around, sun glaring off your graph, bass moving, bait moving, guessing where to lead the fish with a cast, getting your bait down sometimes as deep as 60 ft to them before they move off, keeping and seeing the bass and your bait in the view, knowing how to adjust the graph. My next step will be heavier heads, and freeloader twitching style baits. I see "spot lighting" and catching them requiring a lot more skill, than just going down the bank with a crankbait or jerkbait catching them. I caught 9 on the bank, 0 by spot lighting yesterday.
I'd like someone calling it spotlighting, no skill involved, unethical, not fair chase, jump in the boat with me and prove how easy it is.
