I'd say it's a matter of what you think they will judge you on. A few great pieces with a few crappy could be better than someone with a mediocre portfolio through and through, but if they favor someone with a more stable one you're screwed. You just have to make the call. What did your portfolio look like the last time? You have one thing on your side, and that is that you can show improvement from the last time. Try to empazise that and it might work out.
