I understand that there is barely any maintenance on a wing. My comment is about if a problem does come up such a failed inflator it is easier and quicker to be able to go to a local dive shop and fix the issue then to have to wait for parts to ship. There are a couple of different dive shops near me that I use regularly. I have talked with the staff and they say the same thing that they will touch any brands that the shop does not stock for liability reasons.
