If you want to be a balanced crafter/sniper, I suggest you take one away from PE and add one to EN (so PE will be 7 and EN will be 6).Unless you don't care about EN and if that is the case make EN 4 and add the extra point to PE or IN.If you take small frame, you will only have 45 carry weight, but you will be able to have 6 EN and 8 PE. Pick bloody mess if you have nothing better to pick as a second trait.
I would put them into AG if you want to look at it that way. 8 Luck as oppose to 6 isn't that helpful.
