Supahole, around the time I was starting 5NL (as you are now) I was given a pretty nice bit of advice by yaawn - start your own tables.

HU isn't likely to last long, and you're pretty much guaranteed to get at least 3 droolers on the table before it fills up. Besides, it's probably worthwhile for you to work on your HU and shorthanded game at this stage in your development. Alternatively, you can try joining very short tables (<6 players).
