I agree. I wouldn't bother trying to pick out the cast on edge. It can be tedious and a PITA!! Either just cut the cast on edge off after you have your needles in the destination row (or lifeline or whatever) and then unravel or do what the previous poster suggested by cutting the stitches just below where you have your needle placed. Just be sure not to accidentally cut the stitches that you want to work on.
