I didn't have too much trouble with air bubbles when I installed the Evo slave, although it was a little difficult to get the thing primed initially. With so much air in the line, pumping the lever barely even moved the cylinder. Found it was quicker to pull the cylinder out with my fingers to draw fluid down the line, then push it back to expel the air. Couple of cycles like that and it was ready for regular pump-the-lever bleeding.
It was just as well the bleeding was straightforward, however, because I had to do it about half a dozen times. I couldn't for the life of me get the banjo bolts to seal properly - both at the slave and the reservoir. Everything seemed fine, but the tie-the-lever-to-the-bar-overnight trick resulted in fluid on the floor the next morning. Tightened the banjos a little more, same thing. Bought different copper crush washers, still leaking. Tried annealing the original washers with a propane torch (amazing what you'll attempt at 2:00am when you want to ride the next day), no dice. I ended up ordering fancy crush washers with neoprene o-ring inserts, but before they even arrived I got annoyed and just torqued down on the banjos REALLY hard. That did the trick. But the recommendation to just snug the bolts tight? My a$$!
