I hope I didn't make things more confusing for you. Unfortunately most of the boats you listed (including the Dominatrix) aren't very good in my opinion. You might like a boat that can run decent whitewater (up to class 3 or 4) that also plays well (surfs, spins, squirts.) Examples of these boats that you might find cheap used are listed below.
Jackson Fun or 4Fun
Wave Sport BigEZ, EZ, or EZG
the Dagger GT might be good, but you want to make sure it fits your size.
also maybe the Dagger Vertigo, Ego, or Centrifuge.
Necky Jive or Gliss.
continue to post your options here and I bet you'll find a great boat for you! Good luck, and hopefully we can help you find your match.
