The C6O2 material sounds a trusted foundry material, and hard to get, you wouldn't think it would be so if it was not good stuff. Gary and the people at NFC are trying and innovating things much more than anyone else, if that is not what you want you can buy GLX (30+ yrs), or NRX (15+ yrs), SCV (15+ yrs) technology. Original carbon fiber size on their scale was 160, GLX was designed at 100 and was a real innovation at the time, Gary is playing with stuff that is 8, this means more carbon in the prepeg, no need for scrim (which automatically raises modulus) and less resin (also raises modulus), a denser but lighter material. NFC is not for everyone; they don't try to be. I see no point in complaining when you can just go elsewhere. Why different weights? They are different powers, do you want to see the tips action, or a big bow in the rod? All rods look the same at full load, the more you load them, the more the tip points straight to the load nothing to see there when that happens, thought this stuff would be obvious as you use these things and hopefully bend them also.
