Look, Ma! Two Heads!

It allows you to repair your equipment much easier, but it is still worth a perk slot?
If you want to use the Gannon family or Remnants power armour then it's even more valuable as those sets have terrible item health, but even then i always opt for the T-51b because i dislike having to repair my armor constantly... sodding Deathclaws!Jury Rigging is really not that great, since the ability to make Weapon Repair Kits is actually pretty damn easy, especially if you do That Lucky Old Sun. No, the perk is more for people who use unique, heavy duty armor, like Power Armor/Desert Ranger armor. That's about it, honestly.
Depending on your repair skill, yeah. WRKs are a rarity if you don't plan on scavenging to build them or find the schematic in Dead Money. I'd say take the perk. It's certainly not useless, and it's nice to have the option when your rare armour is trashed.Most of my builds use one of the following for the endgame armor: Courier Duster, Elite Riot Gear, Advanced Riot Gear, T-51b Power Armor, or Gannon Family Tesla Armor. Seeing as Weapon Repair Kits can't repair armor, would Jury Rigging be worth it if I used one of those suits?
Also, doesn't repairing an item with another instead of using a weapon repair kit increase the durability by a larger fraction than if you use the kit?
