Gary spelled out the cf modded flybar nicely. I would take it a step further and thread the ends of the stock flybar to accept the lighted tips. I'm thinking the tap to thread that small would be fairly inexpensive. Probably something you could pick up at Fastenal or any bolt supply house pretty cheap.
That way you will have the best of three worlds , stock flybar with better hub, cf tubes to protect flybar, and lighted ends. Would be pretty cool. The aluminum hub on the lighted flybar will fail repeatedly. Wrong material for that application IMO! Not enough give in it too brittle when flexed.
