9913f7 has a solid dielectric. Conductor migration is a problem with straight 9913, as well as other issues. Minimum bend radii need to be observed.
PL-259 connectors can be applied to f7 with a plumber's torch. Amphenol N's are easy install and easy to come by. Do look for the 9913f7 compatible ones as the center conductor is heavier.
I like Belden as quality is top notch. Flexible and long lived product. Keeping work in the US? Priceless.
A 50' run is not much to worry about. Use LMR-400 DB (cost=free) for the 130' home run to the shack on VHF. It needs no preamp. On the UHF side, LDF450A does better, but needs a preamp.
Try Craigslist for bits of cable. I dug 300' of LDF450A out of a dumpster. Still have 100'.
Tomato or tomato. Do take care as workmanship rules the longevity and weatherproof qualities of the final product. All of this stuff works. Install with a hammer? Not for long.

There is only a .3 DB of loss difference between the regular and flex LMR400 in your 50 foot run. Nothing to worry about. I would just go with the LMR-400-UltraFlex.
