4 ST + WH = 7 ST.
7 ST needs only for miniguns.
Miniguns without BRD? Haha, nice joke!
-> Make LSW build. Take 3 ST + WH or 6 ST + Stonewall perk.
If you want my advice... well... I can't make builds with >1 ST, because I can't get enough SPECIAL to make monster build who can't loot, but who can kill people, so:
#1
( ) - optional
Jet+nuka(+cigs)(+psycho for full fun) = -0 ST (because it can't be less than 1); +2 AP (save 2 perks); +1 AG (save 1 SPECIAL); +1 PE (+8% to hit); -2 PE and +DR to negate Jet (total -8% to hit)
You can easily make 1 ST build, LSW's weight = 9 kg, CA weight = 9 kg, BA/CAmk2 = 11 kg.
Without Small Frame trait you'll have 22 carry weight, 22-9=13 carry weight, -9 = 4 carry weight or -11 = 2 carry weight.
You can carry ~110 .223 ammo with you if you're using BA/CAmk2, and ~220 .223 ammo if you're using CA.
Forget about metal armors, they're not for 1 ST builds, also they look ugly, the worst looking armor in fallout, even bluesuit look better.
SPECIAL will be: ( ) - on drugs
