[TowerTalk] Coax choice for crank-up - looking for TT experience/recommendations

[Alan Swinger]

I have used LMR-400 for 10 yrs with no problems. I attach the coax, rotator cable to the Feedline standoff arms on my TX-472 MDPL w/ heavy rubber (garden hose) wrapped around to ensure the coax is not strained, and let loops form between standoffs when the tower is retracted. 
Good luck.

Seems to me LDF Heliax (either 4-50 or 5-50) won't have sufficient flexibility for the job - the towers are likely to be up/down frequently for neighbour and passing storm reasons. Am I too cautious on that score or is a low-loss coax with stranded core like the Messi & Paolini Hyperflex/Ultraflex series or LMR 400/600UF a better bet?
