Yeah, Rahane was looking very good till that Leg before, was almost run a ball, and has the technique to handle the new ball. May have been very different, but like you say thats cricket - some go for you others don't. But that is why I don't get the reluctance to use DRS. Sure you will also have times when you would have got away with it, but with DRS they give you out, and of course the flipside like Rahane where you are given out but can overturn it. I think the general argument is (pre DRS or without it) that umpire decisions tend to even out ie you win some and you lose some. That may be true, but with DRS at least when you are given out on review, you know you are definitely out (with very rare exceptions where there are still some doubts) and vice versa.
