Interesting - thanks.

Just to revisit this discussion, the current postings of various Phillipson catalogs--even allowing for advertising hype--explain unidirectional fiber very well. I had forgotten, but I guess they pioneered in this technology.

I'm not sure about Fenwick but Phillipson touted the unidirectional cloth in an ad that's in the Johnson book.

I have seen a few rods able to cast accurately with just the leader out, "self-loading" and to me this implies that some weight in the blank other than the power fibers is not always a terrible thing.

Weren't Fenwicks and Phillipsons made with unidirectional glass cloth? And Fishers weren't, Joe Fisher thinking that the cross-sectional scrim added important hoop strength. At least I think that's what I gleaned from the Johnson book.

Great stuff guys, thanks.

The idea of uni-directional goes back to the old benchmark--bamboo--that in its natural fiber orientation is unidirectional. Bamboo has naturally tapered fibers that run parallel and don't overlap. If you think about it, merely by rolling anything around a tapered rod, you can visualize the other problem--eliminating much overlap of fibers, parallel or not, at the inner and outer start/end of the wrap. To exaggerate the problem, try to roll a pice of lined paper into a cone shape (a rod...

S-glass stands for military Spec glass. The glass fibers are a more expensive glass that has about 25% higher modulus and strength than convention E-glass (Electrical glass). As Cross Creek notes, outstanding rods are made from both materials.

Traditional fiberglass and graphite fabric is woven like cloth - half the fibers run one way and the other half run perpendicular (Whrlpools checkerboard). Unidirectional glass or graphite has the majority of...

My understanding is that this is the difference between S-2 glass and E glass, with the claim that S-2 is lighter and makes rods that track straighter. However, outstanding rods have been and continue to be made in both materials--witness Steffen, Scott, T&T(S-2), and McFarland, Winston, and many others(E). I'd say that each rod should be evaluated on its own merits.

Thanks Whrlpool. Any idea how this affects action?

Re: "uni-directional" glass and rod action

It just refers to the weave of the glass fibers--primarily parallel in one direction--in the cloth used. (as oppposed to, for exaggeration, a checkerboard cross-woven cloth.

CTS and pending new TL Johnson rods use unidirectionl glass.

Can anyone explain what this means and its effect on rod action ?

eg how it differs from standard e-glass other things being equal?

thanks
