We had a woeful one last year. Biggest waste of space ever. Turned up as a leg spinning all rounder and took 15 wickets and couldn't buy a run. In my experience, and I've no doubt I'm going to be hugely controversial here but if you're going to bring across a young player, make sure he's a Saffer, if you bring across and experienced player, make sure he's an Aussie. Indian and Pakistani players will work their socks off for very little reward, but in my experience, struggle a little with the social side.
My view is spend the air fare on putting some young, keen players through their level 2, and increase marketing of youth setup!
