I went with something similar to the BabyLoc product (back when I did it I thought there was only one or two brands, not sure if that was true).
I love it. Whole heck of a lot nicer looking than chain link, but just as secure. The self closing gate complies to current code (even though I was grandfathered in since my pool already existed) and I like it a lot better....no more worrying at 11PM if I forgot to close the gate.
I feel 100% secure with it around my pool. I rarely remove the poles to take down sections of the fence, but its nice to know the option is there. I usually only do so to get the cover off in the spring, vacuum, etc.
