Here is the newest version of the composite ferrules. The 8'6" 4 weight went out last week and it sounds like it won't be coming back! So this will be the demo. It's an 8'4" 4 weight.
The more I work with these, the happier I am about them. They add something to the rod that which is hard to describe. I have said it before it removes the hinge that the metal ferrules bring to a rod. On faster rods the hinge provides extra strength and speed, so its not necessarily a bad thing. Soon I will be starting on a 3 piece rod with these ferrules.
