Actually, I just picked up the Crimson Ex myself.....with the way mine is drilled, it is very strong in the midlane. You might be able to get away with the Green Gargoyle, and the Crimson Executioner as a one twon punch for league conditions.
As some may have stated that the Crimson doesn't like oil, you can try a CG out drill and it will work fine. It hits a ton and carries great.
