There is a saying amongst Striper anglers: "If is aint' Chartreuse, it's no use." If you have put any serious time on Striped Bass, Im sure that has certainly held true for you at least once. Sometimes a Chartreuse fly will out fish anything else for whatever reason.
This color in multiple patterns has become a staple in almost every Striped Bass anglers fly box. This fly included. The Robrahn's Bluewater Striper fly is a proven pattern. Bigger fish will typically grab this 4" fly due to its bigger profile. This fly also has plenty of flash for turbid water situations.
