Sri Lanka All Time Test XI

I quite like this as an idea because they haven't been going as a test nation for very long so there's not a massive base, they've had some absolute stars of the game but they've never quite had a full coherent test team so the question was, if you picked from everyone, would there be enough top class players to fill it in every role or would there have to be one or two plodders? The fact Dilhara Fernando is a very realistic option says it all really ... no problem with the quality of the batting line-up though ...
the questions are - does Sangakkara bat and keep (considering how much better his average is when he only bats)? Is Angelo Matthews capable of being the 3rd seamer? Should Ranatunga be brought in to captain? If not, then who? The more accumulative Atapattu vs the explosive Dilshan?
