Hi Guys
For the guys that use them.
After doing some tests on the way some of these are set out and made, i was a little surprised just how little strength this system can have.
I was asked to look into a knot system that would give better strength, as the strength of the droppers varied between the top and the bottom.
When pulling from the 37kg main line loop to the top dropper you could get 18kg 48%, pulling on the bottom dropper it was only a small percentage like 14kg 37%, then pulling from one dropper to the other was nothing short of a disaster.
Also the droppers needed to stand out from the main line at least at 90 deg, this made the knotting tests on the above listed a disaster. A lot of the droppers hang down and close to the main line, the dropper hook and bait can adhere and tangle to the mainline. But a solution was found with good strength, like 82%.
This is a 2 dropper rig, droppers stand out from the main line at 90deg, good strength, only 3 knots to do and can be premade.
No metal involved.
This system should fish better as the droppers stand out from the main line, they can be made as long as you like.
Very good breaking strain low cost. You need to set out all the lengths before you start, from the bottom up.
