I've successfully used Belden 9913F7 but wondering if anyone has considered FSJ4-50B Superflex Heliax for this application.

Subject: [TowerTalk] Coax choice for crank-up - looking for TT experience/recommendations
I'm putting together a new contest station and have already decided on/obtained LDF5-50A for the 150ft runs to the bases of the two crank-up towers.
Looking for real-life experiences with cable choices for going up the telescopic crank-up towers. 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?
