Have you tried using the 580EX in manual mode instead? You can set the power very low so that it doesn't contribute any lighting to the shot but it will trigger the ABs without a problem.
Of course, if you're going to be using the strobe outdoors and need more range than optical triggering will provide, then radio is the way to go. In that case, have you looked at the less expensive alternatives to PW, such as the Bowen Pulsar radio remotes? I personally don't have any experience with them but they are supposedly good alternatives from what I've read. Not as good as the PWs, of course, but good enough to get the job done.
