I've only just decided that If the deck I am using does not have a reversable back, then I will not read using reversals. But, if one were to come up, dispite shuffling so that they all remain upright, then I would refer to the reversed meaning of the card.
ETA: I like and truely believe in using reversals, but I can't stand non-reversable backs making it obvious. This way, I either chose my deck to suit the reading style needs at the time, or I would let the reversal issue go if I wanted to use a certain deck.
