The shank is slightly longer than the TMC403BLJ, so you can try out various fly patterns, and the small barb makes it suitable for large trout. The angle of the vertical eye is carefully set for each size, taking into consideration tying and hooking when beads are attached. It is available up to size #18, which is difficult to manufacture.
