Me: 5'11", 32" inseam, 170 lbs.  Age 37, 17 years paddling experience, would rate myself an advanced river runner, intermediate playboater.  Have owned many different kayaks, freestyle, creekers, river runners.  Have been looking for something that can "do it all", and the CR125 is it.  A real jack-of-all-trades, master-of-none design, it runs down river great and plays well too.  River running: any intermediate level paddler and up will have no problem paddling this in class 4 water.  At 55 gallons it has decent volume and a lot of rocker on the ends to keep you high and dry on drops.  Fast hull, great initial and secondary stability, rolls easily.  I had no problem making my lines.   Like a playboat if paddled aggressively it will perform all the downriver moves, softer edges make it a lot more predictable.   If you paddle a freestyle boat exclusively you will find the transition to this boat very easy, for the most part it handles like a playboat but has more speed due to its longer length, boofs a lot better too.  Did I mention stability - plenty enough for everything but the steeps.  The volume just seems to be in all the right places.   Playboating: does all the moves, not as well but the key here is that it will do them.  I found the CR125 very fast on a wave, carves well, spins, blunts, loops, etc.  Can get onto waves that other spud boats have trouble staying on or even getting on due to its hull speed.  The boat is suitable for ALL levels of paddlers, from beginner to expert, the design lends itself to every type of paddling style and ability level.  Outfitting - great, no complaints what-so-ever.  Can sit in this boat all day with no discomfort wearing river booties, neoprene, etc.  Cone-of-comfort - what a great idea, can't believe other companies aren't doing this.  My heels were always in bad shape from rubbing on the bottom of the boat, with this my feet are great.  Plastic - the boat is very light, I think about 32 lbs, have not had any durability issues or oil-canning yet. 

Bottom-line:  If you can only own one kayak and want to: 1) run rivers comfortably up to class 4;  2) play at all your favourite spots and still feel like you are in a decent playboat (however I do think it excels on waves more than in holes); 3) be comfortable (for me this has become a lot more important over the past few years) then the CR125 (or 250 for the big guys) is definitely the best choice.   I just can't see how they could make it any better, a really superb design!
