I've always preferred straight-hand stocks on my double shotguns and shoot better with them that way. But Ray & Mac are right, a double rifle is a different animal and a pistol-hand stock helps - provided that it is open enough. Those found on most current Euro double rifles are not and I usually notice feeling a bit cramped on the rear trigger. I imagine that a straight-hand stock would be preferable to that, but a pistol-hand of proper shape would be better.
