Since you limited yourself with only ASI armor, you'll need to run with 2 trueshots to be a serious threat. Damage is always preferable to ASI, as you can always get that later in UVs, whereas you cant get damage UVs. You want to kill with as few shots as possible to lower the threat. So unless you fancy yourself an amazing shot, go double trueshot if you want to do more with your shot or 1 penta if you don't want to be 2HKO'd by toothpicks.
