I agree that the Comp telephone dudes are not the sharpest guys to ask about cams. you'd expect or at least hope to get good advice from their "tech" guys but the 2 different guys I spoke with didn't seem to know much more than I do about cams.
Some of the big names in engine building say that they themselves tell the cam company rep what lobe profiles that they want. The pro builders know what works because they see the engines run. The guys at a call center can only rely on what they are told.
