Check out the new OutBurst from Columbia. Just had one drilled, and with the box finish of 1000 Abralon, this would definitely fill the medium-heavy spot in your arsenal.
I've only thrown it for a few games, but in box finish on a medium oil THS, I could easily open up the lane with the OutBurst. I applied a light coat of polish directly over the box finish, and it is still definitely very early, and very strong. My layout is 70* x 4 x 30*, with a weight hole in the P2 location.
I looked at your specs. Do you happen to know your axis of rotation? If so, that would help in a layout suggestion.
