Another thought that worked for us the one time we did well with PC ribs. We made them very spicy. I layered cayenne on the rub then finished with a chipotle/habanero BBQ sauce. There seems to always be a bunch of "chile heads" in a large crowd and once word spreads, they find you and will give you the votes.
