Crossing from SGC/BVG to PSA Question

I have a few cards that I would like to submit to PSA that are in BVG/SGC slabs currently. Is it best to submit these cards raw or to submit them in their current slab? I am afraid to open them for fear that I get a lower grade than I want from PSA. If I keep them in the slabs and ask that they return them if they do not reach the grade I am looking for, then at least I still have slabbed cards. But if I do this, does PSA seeing what another company graded the card at affect the way that they (PSA) will grade the card? Just looking for some opinions.
Thanks!

That is exactly what the grading companies want, more fees.
Anyone resubmitting a graded card to another company for review has to accept the risk/reward reality. If the cards you are considering are high dollar >$500 cards, I wouldn't do it.
Thanks everyone for your answers...
