I am looking for some help/recommendations from the fork experts...I am looking for a used fork for my rebuild project. I was thinking of a rock shox SID but I have read numerous times that they are very flexy for rough trails and especially for those over 170lbs.

I am around 200lbs and am looking for something that is lightweight (3 - 4 lbs) like the SID, again being used, but I am not sure what would be a good option. Looking also to keep the travel in the 80 - 100 mm range with posts for brakes.

what do you suggest.
