Fortunately the XX has been resprung to accomodate our "Middle Aged" weight. which makes a HUGE difference in the enjoyment level.
I am positive that makes a *huge* difference. Suspension setup is key for one, let alone two! Most of our bikes have had some mods to get them set up right.

(Control freak? Who, me?)
At the end of the day though - it is all about enjoying yourselves
