I've had several of these knot up over the years, not regularly enough
to just replace them, just often enough to be an annoyance. I've tried
many types, all seem to have some draw-back. I'm looking for product
recommendations, modifications, anything anyone has done that worked
for years. I can tell you some things that don't work; the rubber
straps with the arrow shaped stops (too rigid), the fluid master black
plastic chain (worst knotting problem to date, it floats hence the
tangles).

Some chains & hooks seem to work well and some don't. With the ones
that don't, I've been able to solve the problem by replacing the hook
with a tie wrap. This works very well and has solved the problem with 2
toilets that I have tried it with. The problem is that the tie wraps
wear through and breaks after a few years. Then you have to replace
them.

I like the idea of the fishing sinker. I'm going to try that next time.
