Comp 268-10

I was killing time on Sunday and I read an old thread where RRR recommended a Comp Magnum Muscle cam for a small block. I was just wondering if anyone uses one on their car and how does idle and run? There are certainly cams with faster ramps and will make more power for the same money.
It has about 12* at .050 more than a factory 340 cam and .020 more lift and I would think it will be easier on the valve train than an fast rate cam.
They sure can't be selling very many.
