? I received Coleman from ERA...4 piston type. The superlights look to be 4-piston also. They seem to be about the same price. I think the superlights look better as they have a painted..baked finish. The Coleman's are not coated. I'm not sure why they switch around sometimes....but it's my guess that both would work fine. Their marketing states.."Willwood"...so they might be trying to stay inline with their literature.
