I've tried commercial vacuum bleeders and pressure bleeders. I even have a spare MC cap with a Schrader valve threaded in the top. I use that for initial bleeding.
But I have never gotten as solid a pedal as I do when you do a good hard and heavy 3 pump-and-hold. Repeat about 6 times. It seems to drive the tiniest air bubbles out and give you a repeatable, high, and solid pedal. No hot fluid(air) fade.
