Claymores and Hurricanes look the best by a country mile IMO, and out of those two I'd take the Claymores on first looks. Vaas and Theron are potentially risky picks as bowlers I guess, and I can think of one or two in the County Circuit who would be good backup to at least Vaas, but other than that the batting unit is very solid.
Looking at the teams, I reckon the Carvers XI looks pretty decent. EDIT: Duminy & Bravo not in great form though, I recall. And a lot will depend on whether O'Brien and Aamir get penalised for not officially playing at the moment.
