OTher thing to remember with "double" jockeys is that thay tend to be described assuming everyone sitting on them is a stick insect!
I have a supposed double - I have to almost have my lifejacke tangled in the steering wheel to make the rear seat sensiblty useable. Likewise I always reckoned the Avon "3 man" as found on the SR5.4 was a comfortable 2 man jockey.....
Other thing with low - whren it gets lumpy, the advantage is you can use "knee suspension" and not worry about the seat slamming your nuts every other wave.
