The stock springs should be 0.46/5.5 , i still think with the 6.0 you will be over sprung , i still think a 5.7 will be the stiffest you might want for your weight unless you are a A rider
Usually the only spring changes up to 210 (without gear)would only be the fork springs and only to a 0.49 , so 0.49/5.5
You STILL did not mention if you had the shock serviced (ever?) , IF that spring truly is a 5.8 it should be plenty enough to support you , i am thinking there is something else (like a shock service needed) as the sag issue unless the spring is less than a 5.5 which would mean someone swapped it out for a light rider , are you the original owner ??
The STOCK spring should hold you up and give good sag numbers (at 235 in gear ,which is as i mentioned about what i weigh in gear) at worst a 5.7 as i already mentioned , i think your going in the wrong direction and putting a band aid on another issue like a oil/nitrogen re-fresh and that can be done far cheaper than a $100 spring i dont think you really even need (do the oil change yourself ,all the info is in the manual and at most a shop should only charge you about $10 to recharge it , so your out the cost of the oil *$20* and the $5-$10 recharge)
I do ALL my own suspension work and have a Nitrogen bottle and gauges , so all i have to buy is shock oil , rebuilding the shock is as easy as doing the forks , with the exception of having the Nitrogen bottle and gauges which runs about $250 , but if you are doing your own *or friends* bikes , its worth the cost
