I don't have to worry about another passenger, my lady has her own bike and I don't plan on having anyone else ride with me.
I placed my order 5 mins ago for the FastGuns and they said they could scoop it out and lower it an extra inch and take the lumbar an inch further back so I would be lower and further back in the seat, which is perfect for what I want.
Hearing that it's a 'Love it or hate it' seat, really has me hoping I'm pleased with it, I'm just really looking forward to a change from the overstuffed pillow feel of the stock seat.
