After tensioning the Phillystran, I rechecked it after a few weeks. I had to
retension. Since then it has stayed the same for several months now..

I assume the jacket on the Phillystran is UV proof? Kevlar does not do well
at all when exposed to UV for long periods of time. It gets very brittle.
How well does the jacket protect.
I also know from my sailboat racing that Kevlar stretches over time as well.
Anyone have any issue with that and Phillystran?
