Def scratch the Ally & Lo-Fi off your list as they're too soft for an "advanced rider," plus boards like the Ally/B-Nice are full rocker and would be too squirelly. The Eminence, B-Pro, and TRS Narrow are all great options for what you're looking for. I'd also recommend checking out the Roxy Banana Smoothie if you want EC2 instead of C2.
