Ditto what reconlon posted. Initially, I had my FF installed on the rear xbar of my TI and found it somewhat of a nuisance to stop pedalling so that I can lean forward to access its controls. Although I went with a different option, mounting the FF forward of or inside the pockets looks like the way to go. Somewhat out of the way when you're working the rails while fishing. And it can be easily installed on the rail opposite to where you plan to bring most of your fish in.
I ended up going with a xbar mount and an extension arm since it gave me the option to position the FF closer to the rear seat or it can be swung to the side to allow viewing from both seats on my TI. So far so good after one season.
