Nick,
As Ice said, we are trying to help, and your last post painted a much better picture, now that we know more.
What kind of smoker, and grill do you have?
When time is short, I have offset on my
Weber Kettle with great results.
Another time saver is 3 hours on the smoke, wrap in foil, then into the fridge. If you know your constrained for time, smoke then wrap and in the fridge (spray before wrapping). Then on BBQ day, turn the grill on low, and lay them slabs in there, even 2 or three high, still wrapped. rotate every once in a while, and after a while, you got wibs.
Another option is to reheat the presmoked ribs in the oven. We do it all the time on long time butts and such.
Membrane tip: Start pulling just a tiny piece back, the grab it with a paper towel in your hand. Pulls off quite easily.
Again, add more info, like you just did, and hopefully we can find a tip or two that works for you
