Been Using Silicone Tubing For A While Now Now Use It On All My Winter Rigs,, And It Can Be Used As A Bait Stop,,And It Works,,But The Cheap Tubing Is Crap,,Will Tear Open Just Ordered Some ,1.5   2.0 mm silicone, For The Winter....
Using It In Place Of Crimps Takes A Bit Of Getting Used To ,If You Have Never Used It Before, Best Use The 1.5 mm , All You Need To Do Is Cut,6mm Of Tube,, Push The Line Through The Centre  And Through The Centre Again,, Then Pull,Not To Hard,,.
You Will Notice The Line And Tube Will Fold Into A Knot, Which Can Be Moved Up And Down.
Something Else Using A Silicone Slider Is Like A Pulley Rig,, The Weight Of The Fish Will Bring The Slider Down Sending The Weight Up Clear Of The Snags,,,,,,,SORTED,,,,
