Went with a specialist keeper, which enables ABD to focus on batting - if I were going for five bowlers I'd pick Swann as well, but it leaves a pretty long tail (not that it should be a problem with the top 6!).
Clarke to skipper as I like his approach to captaincy. I'm not saying that Smith and Cook aren't excellent captains; they are, but Clarke gets the nod for his creativity and he raises his game as skipper.
Would love to find a place for Sangakkara, I think he's superb, but can't look past Amla's current form at 3. Ajmal seems to consistently be taking 5-fers and 10 wkts, so gets the nod over Swann for a bit of mystery as well.
