Duster Rear shocks too short w/XHD Leaf

It is hard to tell as they are air shocks. I know, I know! I just took them back to the auto parts store for a refund. I figured since I have new leafs plus reading all the bad reviews on air shocks I should go back to a normal shock. Now I need to choose which one! I was looking at the following:

- Rancho RS9000XL @ Mancini
- Edelbrock IAS
- KYB Gas a just

I was leaning towards the Ranchos since they give an extra inch of lift, but they are pricey. Any suggestions? Thanks again for all the help!
