There is nothing like having a builder in your backyard when you break something and need another one -right now-! When my boat was flipped in the storm at JPOR, it only took two days for it to be fixed and ready to go. And since most of the F16's over here are Blades, it really is more like one design racing than an arms race. And I'm very happy with my alum. wing mast. I won't pay $big buck$ for carbon. If I had that kind of money, I'd be racing an A cat. $300 for a carbon tiller extension? Spare me!
