TMyers: mine are 1.85 rollers. 1.7 is stock. Another route is the Crane variable rollers like SpinMonster used, which come off the seat much faster so that they behave almost like a 1.8 initially. This is the same concept as an XER-grind cam where the ramp is steeper.
Knkali - I understand.

I use the quick lifts with an XER cam that is near .600 lift on its own. Its somewhat LSK lobe-like in the midlift. They run 1.79 off the seat to 1.72 at max lift. The difference is that the faster ramp on a cam (as per crane expalined to me in an e-mail) is that the added lift from a rocker acts differently than the saem change in a lobe thus being easier on a spring. Resonance issues are less excited by added lift from a rocker than the same net lift ground into a lobe.
Fro those that want to debate the issue, I know nothing first hand of what I just typed. I am repeating what I was told by crane and they will be more than happy to discuss it with anyone interested as I saw in the many e-mails and phone calls I had with them. Please debate it with them if you disagree. I would be happy to hear any new info on the topic though.
