Neither Panesar nor Dalrymple has been playing at the top level long enough to answer this question easily. If the team selection allows only one spinner, then Dalrymple would have to be the first choice because of his superior batting ability. With the current slowness of WI wickets, it might be tempting to consider playing both spinners but that might turn out to be an expensive mistake, particuarly against the subcontinental teams who are good in negotiating the turning ball. Moreover, the lack of bounce of the wickets would be a disadvantage to most spinners and someone like Panesar could go for runs on such surfaces.
