You can read up on the specifics of the trait on the Fallout Wiki article. Endnote 8 free download. Like me you never even use 'too good to use' consumable items like that anyway. FFS, Vegas is accessible on level 1 and you're being picky about some damn trait as.

I am tossing the idea in my head of making a gunslinger build. This is not a standard cowboy build, because he will use almost exclusively revolvers (though I might occasionally make an exception if it is impractical). This is my idea:
S-4
P-4
E-6
C-5
I-5
A-7 (8 w/ small frame)
L-8
Small Frame & Built to Destroy
Now, skills is where I having trouble. I will have guns obviously, but the other two skills is confusing. I want to have the Cowboy perk, which would require melee weapons. I would like to use Lucky, but that would require lockpick. Barter, sneak and survival all sound useful, but don't really bare anything that is much desirable (though The Professional might come in handy). So do you think that guns, lockpick and melee weapons would be good choices?
As for perks, I am pretty sure that I will take Finesse, Rapid Reload (revolvers can take a long time to reload), maybe Run and Gun, and Cowboy (as I previously mentioned). I might give him Lady Killer, but I have not decided whether or not I want him to be a smooth talker.
Any help is appreciated.
