What EDM lifters do you like?

Since I am an engineer for Crower I can say that or lifter are tested via a spin-tron and the dyno every month. We use high zinc and oil with very low zinc. I can tell you with 100% certainty that the EDM lifter will last longer under all conditions than lifter without an EDM hole. Plus it helps when using really fast cam lobes on the street as it acts like a cushion of oil.
