Has anyone tried the Skunk2 Stage 1 or Stage 2 cams here?

I'm curious to know how the idle of the stage 2 camshaft is. Is the idle rough, good, close to stock, unstable or what. I do plan on getting the Springs and Retainers needed with this part too. I'd like to know the difference from the stage 1 and stage 2 cams. I have an adjustable cam gear and VAFC 2 to tune these out as well.

any help with these would be appreciated.
