Ned - the problem with that is that once people 'get away' with doing things a certain way for the sake of expedience - it suddenly becomes the acceptable method of doing it rather than the best. This is the drop in standards and safety that spinwing means.
It is like any line, once it is crossed there is no going back even though 20/20 hindsight tells you that the line should never have been crossed in the first place. It is just another case of money first, safety second!
