Food for thought:

Carbon fiber masts vary widely in quality and utility.

Aluminum masts vary widely in quality and utility.

Aluminum will be lower maintenance and less expensive; opposite is true for carbon.

The superwing mast (on Taipans and Blades) is superb and at the high end of quality for alum masts and the low end of weight for alum masts. It will perform better than some carbon masts and is not THAT much heavier.

I'm not anti-carbon masts and may get one someday; I just want to point out that carbon doesn't necessarily make it better. I prefer my superwing alum mast to tear-drop shaped stiffer carbon masts I've tested. The ultimate carbon F16 mast has not yet been made--I would envision it to be similar in profile and weight to the latest A-cat masts but strengthened in strategic places to handle the loads of twin trap wires and spinnaker use. Until someone designs and builds such a mast, I don't believe there's much advantage over the alum superwing. Gary's Altered has the closest yet (sawed off A-cat mast with wood added to hold the spinnaker), but his mast is a 1-up only mast and I doubt it would withstand the added forces of twin wiring.
