Hi mate, was a little surprised to hear about this to be honest, NOT because I'm too arrogant to accept that I might have got it wrong, but because I can't really see what he means.
As I've always said, if there's a way to close something, then of course there is also a way it could come undone, the best I can do is to make it as unlikely as possible for it to come undone.
To this end, I use only the strongest velcro available, that costs me about £18 a metre, the contact patch is as big as it possibly could be and the velcro is positioned so there is no webbing below it, so it can't
