I think that a Rome Flag 163 would be perfect for you.
The flag is just a wide version of the anthem. They are designed exactly for the type of riding that you want to do. The flag has a lot of pop and turns really well but can really handle speed and pipe.
Like you've been told a lot of wide boards lack performance but rome has really got this one right. I have not ridden one myself but i have a friend who's about your size who has one and just loves it.
Another good option for you is a custom x wide. They are also great boards but they cost heaps more and I dont think you get any more from them than you do from the anthem.
They have the Flag on sale at dogfunk now for a 25% off so they are awesome value.
