I've got an F750GS with the OEM "comfort" (ha!) seat. After a few days away recently I'm really struggling to get comfortable. The seat seems to angle down at the front, and I don't feel like I have enough support around my bum. I think a flatter, wider seat would work better - has anyone got any suggestions? Looked at a few online but they're a lot of money for something which might not be an improvement.
