You've ruled out all the best venues there!
In terms of quality, you're best bet is Forest Rock and The Brand. The trad options at forest rock are pretty limited, especially if you're climbing under E3. There's a much better selection at the Brand, though you need to get in contact with the owner first. She's usually pretty accommodating as long as it hasn't been raining recently.
Beacon hill is also an option if you don't mind stretching your definition of trad to very high ball boulder problems. Best stuff is in the E1/font 6A region.
If you're feeling really desperate Markfield quarry is also an option. It hasn't been filled in (though itd be better if it was) and some routes have been recorded, though they're very much an acquired taste. Whether you'll live long enough to acquire that taste is another matter entirely.
