Exactly my thought, if you need them because you are reving that high, or running that aggressive of a cam profile, then OK. But if not, and they aren't necessary, a less aggressive spring may be better for longevity. That's where I always kind of thought beehives stood out, better than standard single springs, but gentler than duals.

I'm just a cheap ass and always run cheap Crower style singles and don't run extremely high lift cams, or try to rev to the moon.
