There are a ton of great options out there today including the Vision, Star series, 420, Seven0, Project, Kingpin, EZG and more.
From the ones you and others have mentioned so far here are a few benefits of each:
The Vision is a great do everything playboat that excells in both waves and holes. Due to the tucked in rail system it is fast and remains very 'carvy' while still being more forgiving than a totally flat sidewall playboat. River running capabilities are good for a freestyle boat.
The EZG's are a great choice for a forgiving river running playboat that does both well.
The Kingpin as someone mentioned is a classic freestyle boat that has performed well in all types of play features. Also, for 2006 they are coming out with a progresive, affordable price of $799.
The Star series has gotten great reviews from all types of paddlers, won lots of events, doesn't leak (interior mounted outfitting) and also has an affordable price tag.
The Seven0 would be a good way to go for a comfotable, fast river runner that retains top notch freestyle capabilities.
New designs for 06 include the Project from Wavesprt and the 420 from Pyranha. Both look to be exceptional new designs culminating all the recent progression in freestyle boats. Both are currently available for 06.
None of the boats mentioned above are 'divers', all having good rocker in the right places.
Hope that helps..
