I just purchased my first full sinking line, its a type IV wf-5-s. My Q is.... how long of a tippet is used? I was trolling wooley buggers, or dropping anchor and casting and letting it fall and stripping it in. Is there an optimum length so the bug is "inline" with the weighted line as i strip it back in? I used the 9ft tapered mono leader ( the same i use for dry flys) and it worked ok. I don't have any friends that use sinking line to ask... thanks in advance for any input and help.
