For me being patient is a must. Don't give the pocket away, even if you're not carrying. Make your spares and hopefully you'll get a double or two somewhere during the game. At some point the lanes may open up for a few frames and you might be able to throw some big strings for a game or two.
I throw balls that are predictable and rolly but nothing with a real strong cover. I stay away from anything that changes directions suddenly. I may give up a little carry because of the smoother rolling balls but that usually means I'm leaving less splits, washouts and other nasty leaves so it's better over the long run.
I'm 17mph @ 280rpm so I usually start by playing straight up the boards in the 7-10 range. After 3-4 games the middle usually blows up from the higher rev guys and I'll move into the 17-22 range out to 10-12 at the break point. The balls that have worked for me on this pattern are a Spit Fire, Agent, Shift and Zone Classic.
