Sway bars, trd and hellwig

i been looking at sway bars and am torn between the trd and hellwig. I don't currently have a lift but plan to later down the road. With that in mind, i am looking for a sway bar i can use with my stock height and also later when i get a lift. I have read that people have been using the trd sway bar with lifts, but i want to get a hellwig, however they have two versions. The 7889 hellwig sway bar says it is for 2-4" lifts but have also read that someone using it at 1.5" lift. Anybody using this sway bar on stock height?
