Fork spring / oil advice

[mhuffman]

I am planning on getting some sonic linear rate front fork springs. I am 170lbs with gear, and i have a moderate riding style. I was planning on either 0.85 or 0.90 kg/mm. Also, since the factory fork oil is only 10W should i get 15W or 20W?

Thanks,

At your weight I would go with a 15w at the heaviest.

I'm about 15 pounds heavier w/o gear, and I have .90 with 15w oil in my kat f/e. Perfect set up for me.
