Cam grinder/manufacturer opinions

Numbers on paper are one thing...
Knowing what works is another.

Love my Herbert 'Ruben ground' solid roller.
It came with hair more lift but a hair less @.050 dur. I got all pissed at 1st..naturally..then I ran it...DAMN THAT M'FKR PULLED HARD AND KEPT!
I havent really been disappointed by any custom cam I've used...but I have been disappointed using 'off the shelf' cams...always lacked, always needed advanced to get some.
