Here is what I would do. For more backend, I would put the pin somewhere around 4.5 to 5 inches off of your axis. I would make the pin go above the fingers to help it flare more. Put the mass bias around 60 degrees. If you put a hole in it put it low and by the thumb. This will increase flare potential a pinch for the ball to hook a tad more around the corner. Now if you find that this ball isn't cornering hard enough, change the surface. I would first bring the ball to 4000 to make sure it isn't burning its energy early. If the ball still doesn't hook, hit it with 2000 dry by hand. This will give the surface really good teeth to hook. Hope this helps.
