You like the D. And your horizontal recoil info isn't accurate. Recoil type is pre determined by the gun, not perks on the gun. Stability is then what is effected by the perk. Not all guns have horizontal recoil, some drift vertically like the DoP. Just think stability is how much it moves from center (what counterbalance effects) and recoil is the pattern or direction this stability stat moves. Hope you learned something.
