Whether you sit or stand while fishing, you definitely want a mount that raises the fish finders off the deck of the boat for ergonomics, but due to lift, it will likely be in the way for running at speed. Beatdown has good telescoping flex mounts that I almost got until I got a stupidly good deal on the Millennium and can live the minor inconvenience of loosening the pivot to fold down vs the quicker folding setup of the Beatdown. If you need to see fish at distance, you can go either way with Garmin LVS34 or Humminbird MEGA Live 2. Since I'm not looking at the map at the same time as the FFS on the same fishfinder, I didn't worry about having all Humminbirds or all Garmin's. I still have Humminbird 1199s for 360, mapping, and controlling my Ultrex when setting up trolling routes.
