1 bolt or 3 bolt?

OK, perhaps I'm not understanding your guys' definitions. I've gone through at least 100 cam grinds by the following: COMP, Lunati, Hughes, and MP...there's no specific correlation to the type vs duration/lift. Unless you're talking about duration beyond 300* (or 250* @ 050) and lift beyond .575"...or perhaps, solid roller max effort cams.

From COMP cams I viewed in their online catalog, the entire sampling of hydraulic flat tappet cams to include hi-lift extreme energy lines were all ground on a 1 bolt core. Hughes makes both variants on all of the cams I looked up on their site, Lunati will grind them both ways...and MP was really no different-to include their 292 purple shaft, which to me is not a small cam unless you're used to running a .600" solid roller.

While I appreciate the replies, the questions weren't really answered.

Is there any significance between selection of the two?
Are their certain year models that need a particular type?
Are there any drawbacks to running one or the other?
Any experiences good bad or indifferent?
Are incidents like the one mentioned in the original post isolated occurences, or something I'd need to be wary of?
Is there a certain spring pressure, duration, lift, or RPM that shouldn't be exceeded with a 1 bolt? This means, should I not exceed X lift, Y duration, or Z spring pressure with a 1 bolt?

And perhaps a more relevant question-is this a frivolous pursuit? Is it anything to really be concerned about?
