I like Jury Rigging. Love it since when I first pick it. Try to resist it since my third character, but I can't claim success even with my 6&7th character because they are still at their twenties.
Some people knock Nerd Rage!, but its really useful if your always healing with food like me. It protects you while the food slowly heals you. Saved my butt countless times.
Rarely got myself under 20% health, not to mention food healing is quite fast I doubt it would get activate to begin with.
Nerd Rage, the No.1 overrated perk.
