15w is what I used, seems pretty soft for my 250# bulk.
"mmm kerosene... wish I thought of that." - are you mocking me or do you really mean this? For me, I have used white (clear) kerosene to wash lots of things, and it did work (for me anyway) well for these forks. I was also very careful to be sure to thoroughly drain them before I moved on to the Marvel Mystery oil part.
I used to weigh more, but am now down to about 185# - so by my losing weight, the rides seem more "stiff" to me. I am sticking with the 15w because I don't want to spend more $$ on 10w and then take the time to change it.
On my dirt bikes, I used a combination of 10w and 5w to achieve about 7.5w. On street bikes I have used 15w pretty regularly.
