I have a few Lost... boards now and I used to never buy brand name boards. My Mini Driver and RNF are both stock and the RNF is one of my favorite boards I've had in a long time. Haven't really been able to put the Mini to the test but the few sessions I've had on it have been great. Also, have a custom Bottom Feeder. It took forever (3 months in summer) to get but I've had a handful of sessions on it and its been great.
I had a couple of channel islands boards and sold both after riding them just once.
Although, I don't think that either company really compares to the custom local boards I was getting at Hatteras Glass when I lived in Avon. But I live in Wilmington, NC now and haven't been able to find a local shaper/glasser that works for me.
