Preforms are an industry-standard product that doesn't loosen up over time
if correctly sized and installed. You must have had the wrong size,
defective grips, or they weren't installed correctly. I've got a friend with
preforms on his tower and they haven't loosened up in 20 years. Mine show no
sign of loosening up, either. Personally, I think grips are far superior to
cable clamps, which can deform the cable, can be installed incorrectly and
the screws can loosen up over time.

I personally don't like the preforms. I have tried some and I feel they do
loosen up after time. I took them all off and now only use cable clamps.
Cable clamps are cheaper and can be reused or retightend. Just my opinion.
