Virtually the same weight as me,as for my pro pedal I have it set so the rubber indicator ring only moves around 12mm off the shock when I sit on it,That's when I am xc riding, I find that set like that there is no pedal bob at all but you still soak up the small bumps etc etc .When I do trail riding I set it to around 20/25 mm just because there is a lot more technical stuff IE small jumps roots etc etc .
ok sounds like I need to whack some more air in as I think its on 20mm at the moment...
Also - did you find your seat difficult to adjust, I undid the allen bolt but it is rock solid and wont move at all!
