If you are happy overall and just want more power and stability, put a leather grip or some weight in the handle and a little lead to 3 and 9 o'clock. Don't do to much if lead on this wide racket head.
Otherwise, try Gravity Tour for more stability (but less spin and power) or Blade 100 / Percept 100. Maybe try Speed MP but I would recommend trying some weight on your MP to customize to what you prefer if you are happy with the feel and overall performance. To prioritize alternative frames, I would recommend the Blade 100.
