4.5 inch leaf packs...?

I read the big discussion on the quality of rustys leaf packs and it seemed as though everyone preferred RE packs. Which 4.5 Inch pack will net you more lift? I heard the rustys ranging from 3.5-5.5..... What about the Rubes?

I have had mine a little over 1 year. I have always run them with my Daystar rear shackle so I measured a solid 6".

i have rusty's 4.5" leaf packs on the rear of mine that have netted 5" since 8 mos. ago. hth.
