I woud definately say use 5 dpns instead of four. You'll be less likely to get "ladders" of loose stiches at each end this way. You can also knit a stitch or two onto the next needle (temporarily having your work on only 3 needles) each time you move to a needle to "rotate" where your loose stiches will be. Hang in there once you have knit a few rows it's easier.
Nothing is worth doing that isn't worth doing badly.
