I was told in my wet drills that the bow on the left was because the toggle was on the right. So if they were both on the same side there is a chance that when you go to inflate it, that you undo the tape instead of firing the the co2 in the heat of the moment. And the tape length is desined for this.
NOw the next thing that i have thought about is that if the person requires a seat belt extension. Is there enough tape to go twice round?
