Re: Rookie questions, tippets and leaders
If your are fishing a 4 weight line I am going to assume you are fishing for trout. In that case you would want to use a 4x or 5x leader. Tippet is what you attach to the thin end of your leader. This is usually 1x lighter in strength then your leader. So for a 4x leader normally you would use 5x tippet, 5x leader would be 6x tippet. Normal leader length is normally 8 to 9 feet. The longer the leader the harder it will be to "turn over" (basically it will pile and not flip out straight).
Oh by the way, your tippet length should be somewhere between 1 and 2 feet in length.
Hope this helps,
