I believe that AKVX has mentioned in another post that his 5150s were "supposedly a tad long" compared to stock. I dunno if this is a compression or extension measurement.
I have also seen it mentioned here that the 5150s were "more style and marketing hype than substance."
I was eyeballing the 7100s, after evaluating the performance of the Bilstein H1s that I put on the wife's truck.
I'm leaning towards the H1s on the front and the 7100s on the rear with 1.5" of lift. I spend a lot of time on washboard gravel roads and the Rancho 9000s just give up all dampening after a few minutes.
