5X: With no stretch and superior strength the 5X is an awesome nymphing material. It is especially great for Czech nymphing with its super sensitive bite detection.
4X: A general purpose size ideal for hoppers and other terrestrials, especially when fishing tight to the bank.
3X: Stiff enough to turn over bigger flies and superb for streamers.
