Hi,
I'm 6' 1" and 230. I test paddled the Extreme and like SSaKMEMBER found it a little unstable. We have had about 7 CD kayaks between my wife and myself. For sheer stability you CANNOT beat the Current Design Solstice line. The GT is perfect for me. The GT HV or Titan would suit a larger person and the GTS is perfect for a smaller person (like my wife who owns a GT Oracle, similar design to the Solstice but made with new TCS plastics which saves money). I have owned the Pachena (great small boat again very stable) The Storm, same as the Solstice GT but in Poly (much heavier). My current boats are the Solstice GT in KEVLAR. All the benefits of the GT in a lighter package. You wont need anoter boat for camping or short 2 week expiditons as there is loads of room for gear. When camping with other folks I always end up with the extra water, stove etc. since my boat has so much more capacity. My other boats the Scirrico and the Gulfstream. I now only paddle the Gulfstream having sold the poly Scirrico for the Fiberglass Gulfstream, again much lighter and stiffer making for easier paddling and better handling. In my opinion whatever you purchase you can't go wrong if it's a Current Designs boat. I have never been disappointed with the initial boat purchase but have traded up for different application reasons. Figure out what you want to do most (Extended Camping, weekend camping, day triping, etc.) then look at boat design (rudder or skeg) then make your selection based on what you desire most. Buy it, paddle the heck out of it and then, in time decide where to go next. I am still seeking the elusive single boat that does everything well. I think I may have found it in the FG/Kevlar Gulfstream. Good luck in your quest.
