It is hard to judge what England want to get out of this series. Looking purely at winning this series, Ali has to play over Bess. It obviously isn't an all out effort to win though as we have the squad chop and changing (I can't see us running the squad for the Ashes without our best players being their for the entire series). For the long term, Bess would be better for the experience.
Assuming that Crawley won't be fit and the pitch won't be a dust bowl, for the first test I would go with.
