Re: Allen rods - ferrells?
Dean, its not neccessarily stronger, its just to have the ferrule flexing along with the rod whereas tip over but tend to feel flat and dead at the ferrule making the tip section feel like it hinges. Atleast that's what I understand, pertaining to glass rods. Graphite, I suppose they same idea applies if a a material like a glass/graphite composite spigot is used.
