Well the reason i asked, is due to all the pics you posted being taken in Stick Marsh, not farm 13 where most trolling is done.
Ive never seen anyone trolling in the Stick Marsh side, no doubt due to obstructions.
There is deeper water as you know on the perimeters, but also much boat traffic.
But i have considered doing so by pushing shallow lines or even both by using floats.
So back to my question, Farm 13?
