Scrap the law? In short, bollocks. I think Reverse Swing is certainly attainable without ball tampering and am of the opinion that if you aren't good enough to be able to reverse it in normal circumstances, why should laws change to make your life easier? It would reduce the effectiveness of world-class reverse swing bowlers such as Simon Jones as any old bowler would be able to do it, instead of spending time mastering the art, as Jones had to.
I also dislike the suggestion (apologies, I cannot remember who said it) for the new ball to be available after 60 overs - this would reduce the role of spinners in the game, something I would not like to see.
