I’ve gone through all the tippet to find ones I like the best (the leader material) and inadvertently analyzed the design of the spool tender bands.
The rio elastic with a hole is my favorite, as long as the tag end does not get lost inside. Then it’s a pain. The best part about these are that you can rewind the spool if your tag gets too long. Also the size printing is nice.
The trout hunter rubber is two different bands and they are thin. They work great, except you can not rewind them. Also there is no “knob” to pull on to get the band off. I have to grab it with hemos. There is no size printed - you have to memorize colors. This sucks.
Cortland has elastic with no hole. The stitching usually snags on the tippet and this is annoying. No size printed and again, colors.
SA and orvis both have rubber, single layer with the knob that makes removal easier. There is the size printed on the band which is nice. No snagging.
I’m sure there are aftermarket ones but I haven’t explored those. I am also refilling floro with segaur, or putting cortland from a guide spool onto trout hunter to fit into my C&F pack.
