what shocks to run in the rear w/ lc coils
 

i've got a pair of lc coils coming in and i need to know what size and type shock to run. Ive got some horrible brand x's on there right now and im running about 3.5 inches of lift (coil spacers and airbags) on stock length shocks and it rides like poo. I dont really want to run these with my new coils. Ive heard that rancho 5009s are too stiff but i cant exactly spring for the 99009's.
any suggestions?
