Need some help re suspension..

..I think I am going to put a poly set front suspension kit into the duster really and I am leaning to a set of sway bars..

I really want this car to handle safely because of it's cargo.

I see Jegs uses a brand called energy and addaco bars..I see that PST is an advertiser and I see there kits all over..and they also sell a set of front and rears..

How is pst againt the other ?

Comments , opinions please.

Thanks

Ian.
