Best method for NPC weapon physics?

[Mookeylama]

i had been using the old Everyone method and i'm pretty sure it is causing some of the lag and script stacking i experience. i see there's another method which seems to use a cloaking spell to equip a weapon physics sling on npcs in close proximity to the player. but i'm not thrilled w/ cloaking spells either lol

so which method is best for weapon jiggle?

also why exactly was the "everyone" method abandoned? what problems did it cause? thanks
