In the individual's defence and in my experience, while he could occasionally use the long screw driver, he was a very capable and intelligent bloke who would give support when it mattered. Yes he asks for a lot, but he would give you the opportunity to do things your own way and can accept counter arguments as long as they're well argued and based in fact. Not an expert, but the arguments for provided above make sense and as is said above, what we've got at the moment isn't producing the goods, so why not try something else?
