Level 30: Almost Perfect
Though the extra 20% gained from stimpacks due to Fast Metabolism is helpful, as a stealth character with an evil prerogative, you have MANY stimpacks. The ability to shutdown a robot in stealth will be more practical. If anything, pick up Fast Metabolism down the line.
Also, starting at Level 21, maybe go back and get Entomologist instead of giving into a skill-related perk at this point! It may be more useful at this point in the game.
