How old is your youngest account?
You should get a boost when the youngest one turns 6 months, and again when it turns 12 months.
It's definitely tough getting in with a decent card after BK. They really (and understandably) want to see a track record first.
I'm thinking that the longer that you can function with what you have, showing stability and self-discipline, the better for your future chances.
But I don't have a lot of experience in this area, so I will defer to others. (And I assume that you're familiar with the BK-Friendly thread stickied up above.) GL
