i can say this from doing it that a 4 link is 100% better that leafs it makes the rearend alot tighter, and for the bags its all in how its done I am trying to remember but I think bags in front of the axel gives you better ride and putting them behind the axel it better for towing i think over the axel is the worst ride from what I have rode in and the first one I did was over the axel and it wasnt bad but after ridding in one with bags in front of the axel I could tell a differance. and the psi to raise bag depends on the size of the bag
