I've seen them at the sports shows, they look promising. Freedom Hawk kayaks are more popular in Florida and the Texas Gulf Coast, out in the flats. I haven't heard any negatives about them other than being heavy.
On the flip side, you can stand and fish in a Hobie Pro Angler and y-shaped pontoons are needed, but a PA is ~$2k. It is the fastest kayak I have ever been in.
Standing up in a kayak is overrated, all you need in California a super comfortable seat like a Surf to Summit Expedition and an ICE COLD BEER, unless you are sight fishing Fall River or somewhere like that.
If you got the $$$, BUY IT! and post a report on
