I'm seeing a lot of posts of late advising people to forego traditional tips and instead use sinking poly-leaders. I have used the poly-leaders off and on over the last few years and love the way they cast. From my experimentation though, they do not get down like a tip. For intermediate and slow sink (think type III) applications, I think they have an use. For use in place of Tye VI, VII, VIII or T-14 tips, I haven't found them to be as effective. I'm curious what others results have been using these.
