The ballhead tube from Eumer is small and lightweight. The ball is a strike point and a weight, so it reduces the need for a shot ball or a conehead. They are excellent for bead head nymph patterns and quick and easy egg sucking leeches. The ball basiclly replaces the "thread head" on a traditional fly.
The Eumer ballhead tubes are sold here in the 17 X 4mm size which weighs .07 gr. Colos are fl. pink, fl. red, fl. yellow, orange, black and gold. 10 per package and come with liner tubes and junction tubing.
Use the gold (not pictured) for standard "bead head" nymph patterns!
