Ace T-Tips are used to quickly adjust fishing depth without changing the entire line. The 10ft, 12.5ft, and 15ft lengths let you choose between a more maneuverable tip or a longer, deeper presentation. The T10, T14, and T17 classes adjust the sink rate and how the fly holds in the current. Pre-tied loops simplify tip changes on a compatible head. Weight and length markings on one end help you identify the correct tip in the pouch.
