Guess I'm just greedy, Richard. I genuinely can't choose between two of them, although obviously they have different traits. Bit like asking which is one's favourite shirt, I suppose. Depends on whether it's for a black tie event, a lounge suit or for work. If there were a fire, I'd save the M21, but that's a bit unfair as I'd be taking it because it's irreplaceable, not necessarily because I prefer it.
