how do you guys use your free submissions?

do you submit cards that aren't worth the value on a normal submissions or do you send in the more valuable ones?
i am renewing my subscription here soon and just wanted some opinions. i have a few sets i would like to start grading and not sure if i want to submit the commons first or just go with the better cards.
thanks
