Dear all;

I've seen the Skyshark carbon rods, the "rolled carbon band one".

Can you tell me what are the difference between these rods and the classical
ones?

The one negatif I can see is that they break easily (From a friend point of
view, using a blackbird kite...)

Thanks for your comments,

Luc

Wrapped carbon (as opposed to pultruded carbon) rods are in general:
 - Lighter
 - Stiffer
 - More fragile

But we can be a lot more specific than this.  Go to http://www.kfs.org/kites
and look for spars in the reference section to read up on the valuable
practical research conducted by Simo Salanne, David Lord and others.

	The rolled carbon spars are well, rolled, instead of extruded.  
They tend to be _very_ rigid and break easier.  Two wrap or three wrap is
usualy what I use, they are heavier, but don't break as easy.  
	What ever you do, wear gloves when dealing with broken carbon spars.
The splinters they give are worse than fiber-glass!
