I still didn't get the exact technique you used to bleed the brakes, but would suggest ditching the speed bleeders if you haven't already. I'll give you my procedure if it helps.
To bleed mine I first crack the always-sticky bleeder and tighten it back up loosely so it's ready to go. I put a very tight fitting nylon clear hose on the bleeder and put the other end of the hose down in a clean glass jar with a bit of fluid already in it. Tight-fitting means that after the hose has brake fluid in it, with the bleeder closed you can put a vacuum pump on the end of the hose and not see bubbles coming into the hose from around the bleeder. It may also help to cover the bleeder threads where they screw into the caliper with a blob of silicone dielectric grease to make them airtight.
Start by sucking old fluid out of the brake reservoir if you have a pump and refill with fresh fluid (you don't have this problem with all the fluid you've put in there recently.) With the brake caliper's hose submerged in the jar, crack open the bleeder just enough that fluid will flow (less than 1/2 turn), then start the car so you have boost to help you, pump the brakes once or twice and check the level of fluid in the master cylinder reservoir vs. how much more is in the jar - NEVER LET THE BRAKE RESERVOIR GET BELOW 1/2! (this is easy with ABS because of the bigger reservoir.) With the end of the hose submerged in fluid, even if you do get 'suck back' when you release the pedal, it won't be sucking air back in to the caliper.
If you have persistent problems with symptoms indicative of air in the system, you might have an air bubble in the lines that just won't come out the other end. You could try 'speed flushing' (tm) to force it through the lines - with the bleeder open even more, have the car started for boost and have a buddy ready to pour quarts of brake fluid in the reservoir. Then just pound the **** out of the brake pedal repeatedly while pouring brake fluid into the reservoir until the system has pumped through a quart or two of fluid - the high speed should hopefully take any bubbles out the other end.
