Im also using 5 cables and around a Tailtwister rotator.

I turn 1/2" Cellflex cable which is similar to FSJ4 for more then 30 years
and never had a problem.
On one tower I turn a bunch of 5 cables at once.
And yes, never damage by critters since using that kind of cable on all
bands, also as feed lines for beverages.

More of a topic for a VHF/UHF forum where the question comes up often..
I use that coax on the mast and to power dividers and out to individual
yagis but it certainly is not meant to survive long around a rotator.
There
I use LMR400UF and into a 50-75 Ohm coax line transformer into .75 to 1"
75
Ohm CATV hardline for 144 MHz and higher.
Another line transformer converts back to 50 Ohms in the house to keep the
several Bird 43 line sections and elements happy.

This would be a natural topic for Tower Talk. Access via contesting.com

I'm thinking about replacing the lmr400 with fsj4-50b heliax since I
have
several thousand feet of that on a reel. I'm also thinking that the
corrugated copper shield will resist critter damage better than the
braid
in the lmr400 cable.
