Mamba creeker 8.6 or Phantom

Now that I have ruled out the Machno (b/c I am in between sizes) and have sat in the Mamba and Phantom (I fit both well), I would like to get some feedback on these two boats. I am tall and slim 6 foot 4 inches 185 pounds, size 12 feet. While I have dabbled in harder whitewater, I have mellowed, and now keep it to class III-IV runs. For creeking and harder big water, I used to paddle a large Karnali till it broke. I liked that boat, certainly more than the Nomad that I replaced it with...
