I am one of the guys that think the base carbon frames are to bulky. This will be more of a problem as the sizes get smaller. I would like to see some sort of carbon composite used to make a more molded type guides like the ones shown in the link below. Now these are titanium but they also make or are making the same frames in a carbon composite. These are sleek and attractive. [imanangler.com]

Zenaq is still working on the carbon composite guides. However, they do not plan to introduce them in more than 3 sizes and none of those will be small ring, low frame single foot guides. Those types remain best suited when done in current stamped metal types. The company's idea is to mate current low frame single foot running guides with 2 or 3 high frame carbon composite guides.

I have yet to see a composite guide that I think is attractive. They are all too bulky looking for my taste. Different strokes. . .

Check the Zenaq guides. Very slim and sleek. The carbon versions look just like the Ti versions but maybe a little slimmer.

I have seen the Zenaqs, still don't see a carbon fiber guide that I would like to use. thanks, though

Sleekest guides on the planet. But to each his own.

I guess it depends on one's definition of sleek. To me they still look cumbersome, thick, not in any way elegant or sleek as are many metal framed guides. But you are right, to each his own.
