Bill Dedman 1.6 didn't make much difference but i find rocker ratio in my program usually don't make much difference so i wouldn't use that as a deciding factor especially after what PowerWagon896 said.

In the real world, rocker arm ratio make a difference.

It allows faster opening of the valves W/more lift.

In essense it gives some of the benefits of a "bigger" cam W/O the drawbacks of more duration.
