This odd-looking bracing system - I've cropped off some of the oddness :-) - has an interesting feature, in that the main part of the bridge plate appears to be the same material as the top, but with this difference, that a piece of carbon fiber has been inlaid where the ball ends will be pulled up against it.

The cf is very light of course, and very hard - what do you guys/gals think of the concept?

If it sounds good and works for its intended purpose, I think it's great. But one has to decide if what seems to be the extra effort to install it is worth it.

This is an opportunity for an engineer who is familiar with composite materials to speak up.

I was just pointing out that, if a brass plate is a viable option (and to many, it is) then something lighter and tougher, CF, might be viabler. (Yes I made up that word). The extra effort would be minimal I would think.

Dave, I think you're making a very valid point. I just don't know whether c/f sheet is good stuff to take point loads at the edges of holes in it. For sure its inflexibility would stiffen the bridge plate's bending under string tension.
