Glad you got the bug....as you can tell most of us have a serious whitewater addiction too....and there isnt a better fix then getting out on the river...
so here's gonna be the general consensus from most. you want a stable river running initially. i would not recommend the dagger playboat, or any playboat right away*. with the caveat being that everyone's different, and if you have a decent roll already then you have what you need to not endanger yourself too bad paddling a little spud boat.but it will be scary sometimes.... playboats are somewhat squirrelly and designed to flip very easily, to do all the rad freestyle stuff. thats not to say you cant really get after it if you are that type A personality, but its like learning to surf on a shortboard instead of a long board...harder.
the real deal is you will want at least two boats very soon...a river runner/creeker & a riverplay / playboat. some folks just want to cruise,and willl never need a second boat.
but...it sounds like you want to get after it playboating too, (which is crucial to becoming an expert boater. rolling up from every which way)
So #1....the best river running boats are the LL Remix, Jackson Zen, WS diesel, Dagger Mamba.
Jackson Hero/ Superhero, diesel, mamba and nano all creek really well too.
#2...Playboats... JK Allstar, pyranha jed, dagger jistsu, WS project.
To narrow it down to two best all around recommendations imho...JK Superhero & LL Remix.
The best playboat imo.. JK superstar...
(but i am biased to Jackson kayaks and own the Superhero and Superstar...) never been in any of the other playboats listed but they are all really awesome boats.
wow. next time two word answer. HERO & Remix.
but there you go...!
Hope that helps, seriously, demo boats, and get hep outfitting them to fit you properly...you wont regret it.
