I have thought about trying a rubber but, I think it would just defeat the purpose of how it works compared to how bands work off a line.
I find that twisting my braid 3 times , once I start cranking up the downpressure , the line slips after a few minutes making me think it released, so now I make sure I twirl in on my
finger 5 to 7 times then slip it off my finger onto the pin.
And I love them compared to a scotty pinch clip.
I will also say, that if I had to order again, I would be trying this Quebec place as its just a few more dollars and if you take a hit from Canada post its 15 at least.
