I had the same problem when I first got my kegerator - Petro Gel and good metal hose clamps (instead of the cheap plastic ones that came with the rig) fixed me right up, I'm on Kegs #9 and 10 on one tank with plenty of Co2 remaining.
+1 for Whirfloc and no filtering. I can read the computer screen through the one I'm drinking now. However, if you like filtering - go for it! I'm in complete agreement that a little extra time is worth a product that you think is superior! :mug:
