I admit I have no experience driving a /6 yet :).... but the modeling I was doing for Doug seemed to match his real world experience with his grinds. The RV10 is what I would use for something that you just want to drive. The RV15 breaths a little more above 3500-4000RPM but gives up a good 10-15 ft-lbs below 2000 RPM. Other than that they are close.. The Oregon Cams is in the middle... Is the one you are quoting the 2106? Do you have the data for it? I can run it in the model. In the model the sensitivity to similar cams is not high, my prediction is the under normal conditions I would predict you could not tell the difference between the RV10-RV15 and OG 2106 unless you where in a place where you were kicking it in the butt to pass someone and the RV15 would not die out as soon.
You are correct there i a lot of smoke and mirrors in spec sheets and the way cam companies talk about/spec out their products. The duration at 0.050" lift was one attempt at making it apples to apples but as you state there are other terms the companies use that make it confusing and make their stuff look better.
