I personally have found I dont like flip-flopity seats..Thats why I have relocated my batteries and then making my seat solid..and when you do that you can lower the seat some to reduce high center of gravity...
My old tractor had a solid mount seat, and it was great for stability, but if you do any rough terrain at speed or (God forbid) jumps your back will be less than thrilled with you. Voice of experience.
