If you do decide to switch to Senna seats, be careful with the choice. Dalton said mine are the narrow chassis, I was previously unaware that the chassis itself came in two sizes, but they are extremely narrow in the hip area, they fit me perfectly but a couple of people who've tried them were unable to sit all the way down. It's not the pads either, they have the thin pads. I'm probably going to get some softer side pads made for the passenger seat.The P1 seats I find super narrow in the hips. I wonder if there is a way to take some padding out in the interim while I find a more permanent, economical solution. dont feel like dropping another 10-25k on just seats. I can live with the P1 seats if I have to. Not the end of the world.
