My
TCI setup is on single adjustable Ridetech coilovers. It handles like it's on rails, and with the adjustable rebound on the shocks, they can be turned down to be more comfortable on the street. The old 4.5/6.75 drop I had before was similar to what you described, and bumps and potholes at highway speeds made for questionable events. The truck would jar, shake, and wobble on hard bumps and such. Now, potholes and bumps are absorbed like a newer car, and there's no drama involved while driving. It's very smooth, but still has crisp steering response.
