I don't think Joe Average needs needle-bearing fulcrums w/ a pressurized shaft rocker system. Needle bearings are applicable to applications that rely on oil splash / mist for fulcrum lubrication. A plain bearing setup on a pressurized shaft distributes the load better than needle bearings, even if it doesn't look as sophisticated.

We ran stock OOTB Crane gold rockers with a UltraDyne .613 cam and the suggested springs and never had a problem,and they had been used for 5 race seasons before that.
