I've never tried the Crower aluminum rockers but Crower makes really nice stuff and their steel enduros are my favorite. I likely wouldn't be afraid to try any of that stuff made by Crower. The Comp steel rockers I've never seen an issue on the street engines I've used them on. Been a while since I've used them till recently though when I couldn't get the Enduros.
The engine I'm doing now I bought a set of Ultra Pro Magnums because I was told Enduros wouldn't be available for months (this was 4-5 months ago) The Ultra Pros have the oversized trunions, extra retainer clearance, and made of 8650 chrome molly. I don't think I can hurt them with a hydraulic roller on this engine. In fact I could get away with less but I tend to like to overbuild a bit for added insurance.
