I cheated, it's actually a Custom Buell Service sourced damper kit with a custom isolator bolt so I didn't have to drill and tap mine, for the cost, I couldn't pass it up. So far, seat is ok? When I was street riding it was a bit stiff, but I could also move and change pressure points so not horrible. On track I try not to sit. I haven't thought about it while racing so I'll take that as a win.
