Rear suspension....what to do???

[vroomy]

Hey guys i finally have my truck on the road after doing a LS swap. So now addressing the rear suspension. It sags pretty bad on the left, already done a diff flip and reckon another inch or so lower would be just right. So far im looking at a set of composite leafs from ridetech or installing the air over leaf setup also from ridetech. What would be better or is there other options out there? Its an everyday driver so im wanting it ride well and handle as good as a truck can, definitely like the low look but needs to be useful and usable.
Any help and ideas would be awesome

Id put up a pic of it but got no idea how to do it
