owned a high performance epoxy longboard from lanny schuler in oregon for about four months.... only sold it so i could get a fish and am now wanting to get another as a complement to my heavy single fin.
overall it weighted about as much as your average polyester shortboard. this one was real high performance and well just a lot of fun.... even managed to get on the nose with it.....
finally to durability, lanny's boards are great.... you can throw them off a house and still not have a ding.... the only times i have put a ding in one of his boards are a) when the board came of the car at 50 mph and

when i slammed into some really pointy rocks of a reef. if you notice the theme it is puncture damage is bad, but blunt trauma will not affect the board. this brings up ding repair. epoxy kits are not that hard to find, but that said lanny was actually telling me that he likes using polyester resin mixed really hot to do some repairs on his boards since he gets this melted bond on the injury. that said he is a bit of a mad scientist and well this repair approach maybe should not be attempted on your own.
ps i ride one of his thrusters when it is real good, and well it is a great board too...just which i encounter waves that required it more often.
