i have been working on sweeps for a month or so now and i have the tech itself down but if i go above a 3 string sweep i get all the extraneous noise of the unmuted strings, im working on the finger "roll" to help with muting but what else can i do?

i have an omen 6 with 10s and the action set pretty low. Would my action be a factor in the extra noise?
use your picking hand to mute the strings above theone thats supposed to ring and your fretting hand for th estrings below it

by above and below i mean closest to the ground
