boarders paradise in rocklin has everything you will ever need. They have all the new stuff and all the old stuff on sale. Its right across the street from the Land Rover dealership, and next to the huge cal fit.
Make sure you talk to Tanner at Hot H2O, they dont have Hyperlite but they fully stock CWB and L.F., badass shop, and yeah centurions are garbage. Surf and skate is of the kids dont really ride. Boarders paradise or Hot H20
Waterski World is also a great shop. Good people with a great return policy if you don't like what you get. They have been very good to us over the last couple of years.
Waterski World does have a demo program, but I'm not sure what it is. We have always just bought and exchanged if we didnt like.
Boarders Paradise has a demo program too. You pay $150 to demo 8 boards. The $150 goes toward the purchase of your selected board. Or I think you can pay $15 per demo but the cost isn't applied to any purchase.
Larson Marine also has a demo program and is located in folsom right off 50. Im shure they carry the whole hyperlite line and 95% they carry CWB. They also have an awsome return policy i think you can bring the board back even after riding it.
