HyperU's need to be installed correctly or they'll fail. This is the major problem with building an engine with these. I've never had a problem with them.
While I like Comp Cams alot, shopping around for whats out there never hurt. If you want an aggressive ramp, other cam manufactuers offer more aggressive ramps than the extreme lione of cams.
Also note that Comp Cams themselfs have more aggressive cam lobes than there extreme line.
