Best rocker arms ?

A lot of people like the aluminum rockers, but i personally prefer the cast iton ones. The factory used them in all of the mechanical cam engines and expected them to last the life of the engine. For the price I think you can't go wrong with the Crane rockers. I am presently using an old set of Isky's that i bought on ebag. Paid $120 with shafts and pushrods. I'm totally satisfied with them. The roller bearings that some alum rockers use just don't last and who wants a bunch of those little rollers bouncing around in their engine?
