David,
I think the problem with the Eatons is they can't go past 10psi. If you strapped on the 112, I think the airflow at its redline would be pushing air in at 12-14 psi.
Yeah, I'll happily pay the extra for the MLS gaskets over copper. The many hours of labor to re-torque is worth the few extra clams. If I can ever get a break from work.... :(
