Wax, do you know how long the bic lighter spring is, by any chance. I have a couple old bic lighters, but i'm asking, because i also have probably' 30 or so old lighters , like a bic. I took one apasrt and the spring is aboutan inch long, and i'm guessing about 1/16 th" in dia. Welcome to have them if you can use them. I don't use them anymore....!
I snapped the end off one of my St Croix rods this week adjusting the spring bobber...talk about a bummer!!!
What I like to do is when you get a fish right on top of your lure, really slowly raise it up and your spring tip will start to bend and it has it swallowed. I noticed I need to do this a lot when using flies but they hit it hard with jigs. Dunno why.
