I like my air bags, can adjust to different weights
PS have seperate air fillers for the bags. one for left one for right side...
PS 2 I fill the bags till the helper spring lifts of the pack, them let the air out till it just toughes the pack again. that way their both working together ,, air bags and the helper springs.
