I am not being critical as much as I am curious. And I am certainly not the final word on anything that happens outside my garage.
Just struck me as being pretty tame spring pressure.
Ramps have a ton to do with requirements too , though I think force fed motors like an early and quick opening on both sides and a wide lobe angle.
If it works , that is what really matters.
And I do tend to be the over build kid in a lot of instances. A nice fat margin for error never scared me none.:-D
