It's a great kayak to learn whitewater on and is used by many instructional classes. The round hull design offers little primary stability, but the secondary stability is easy to work with. The benefit of low primary stability/rounded hull is it makes rolling the kayak much easier. I had significant trouble learning to roll my old Eskimo Quatro ("river runner") because of the flat hull and high primary stability. After a few attempts, I completed my first ever whitewater combat roll in the Overflow X, which allowed me to paddle with increased confidence and to take my whitewater paddling to the next level.
This is definitely not a "playboat", you won't be squirting, cartwheeling, or hucking in this thing, but if you want to safely run rivers, gain confidence, and have a kayak capable of dropping waterfalls, this kayak is worth considering if you can find it used. (I do not think they make it anymore.) If you are not a large person, then the smaller Overflow would probably be more to your liking.
