The district is a great board. I don't think you would go wrong with it. I demoed one a few weeks ago. Speed and pop were both decent and it tracked well without any surprises. The Response is also a good board, but with the flex core, I don't think it will be as predicable as the district. It will have softer landings though, if you start jumping the wake.
I also know Travis Moye, who runs The Boarding School is also a big fan of the District too.
