Robi,
I used this system myself and I found a larger loop makes it easier and therefore quicker to hook up.
Never had any issues unhooking.

Only real issue is that is will fail eventually. I think it must be the fibres cutting one another where the hook loads up the line. Replace the line once a season and this can most likely be avoided.

Regards,
Phill

I know that the voices in my head aint real,
but they have some pretty good ideas.
There is no such thing as a quick fix and I've never had free lunch!
