The BPS kayak uses the old Tarpon molds. As far as getting oil canning on a plastic kayak with a relatively flat bottom - that's pretty much universal whether made in the US or China. All plastic kayak bottoms are flexible.
Check the reviews for leaks or wear through, but don't get yourself tied up in knots over oilcanning on a recreational kayak.
As far as whitewater, it's not a whitewater kayak. I know plenty of people who took the old Tarpons through WW up to class 3, but that's not what it is designed to do. And you sure aren't going to PLAY in a class 3. You would be able to RUN it if YOUR skill is sufficient.
