Favorite bobber stops for slip corks
So I have always used the little plastic things you weave your line through 3 or 4 times (paired with a bead) as an adjustable bobber stop. I'm looking to branch out a little both because it good to expand on skills but more importantly I'm trying to find the best option that will work for my kids' reels. My oldest are twins and finally want to move on from the spincasts and go to spinning reels. Probably start with 100 series sized ones. I still have two younger ones who will be on spincast for a good bit longer. Not sure you can even make a bobber stop work with a spincast but Im all ears if anyone has an idea there.
Anyways, I've never been a big fan of those pre-tied yarn ones. Few times I tried them all they did was slip on me. I'd much rather tie my own but what do yall use for that? Ive seen some fellas on youtube say dental floss but Ive then seen others swear floss slips just as bad as the yarn or the bead wants to slide over the knot.
How well do the rubber ones work? Any other options Im not aware of?
FWIW I typically spool my crappie/panfish reels with either 4 or 6 lb flouro in case that has an impact on which option works best.
