Might as well give it a try...
I started trying ADV as soon as it was implemented on PO, as I've never been able to run NBS. Unfortunately, before the tests were live, the ladder was dead, with no more than three people on at the same time, and towards the beginning were almost all BP team, which got quite stale after a while. In general, I've been told my team is pretty solid and I believe that I know the metagame reasonably well, certainly well enough to decide whether or not I believe BP is going to be beneficial for the metagame during the ADV portion of the Smogon tour.
