Rather than drill to mount a low back seat, or sit on a sliding cooler pad, does anyone use one of these flip seat brackets? Is it a PITA to flip the seat forward to get into the cooler? Is it a good design for keeping your cooler from getting four holes drilled and sealed? Now that I've got a cooler in my rower's bay I'm probably going to just sit on the cooler until I figure out a way to get the low back seat back into play. Thanks for your thoughts.
