Spring size vs weight

Doggy

Inconceivable!
I have just picked myself up a new Norco Atomik and it came with a 500 x 2.5 rear spring. I knew this would be too soft for my weight so I was expecting to buy a different spring. The question being, what weight spring for my weight. Im not exactly the smallest and 6"2 and 95kgs so I was thinking around an 800 maybe??? I intend for this bike to still be ridden around most of the day so if I can limit the pedal bob with the heavier spring and still have it right for our downhill tracks as well.
Would the 800 be too much? or does that sound about right:confused:
