I don't know why this is still a debate. The manufacturers are nearly in universal agreement--double stow. Virtually every manufacturer out there says this. By contrast, I don't know of even one major manufacturer who currently recommends against double stowing rubber bands.
Bag strip is a very serious malfunction and if it happens to you there is a legitimate chance you could die from the resulting hard opening. Double stowing is explicitly intended to prevent a bag strip malfunction and it is more effective at doing it than other forms of stowing. At the bare minimum, if you dont double stow you should be able to easily lift your bag off the ground by the lines without them falling off. If you cannot do that, you need to use a different stow method that provides greater stow tension.
One of the problems that makes single stowing seem attractive is that the problem that is created with single stowing does not immediately manifest itself. You could go thousands of jumps without ever having a problem. But one day out of nowhere the physics align and you get slammed like you just got into a car accident at 120 MPH. That would be the bag stripping off the parachute causing premature inflation because your locking stows were too lose.
