like Sean said, a good ride is very dependent on the perception of the guy driving.
I would pull the jounce bumps out and see how you like the ride at the lower level. you may notice a bit of floatyness from that though.
if its still rough, i need to know where you notice it riding rough (type of road, what your hitting, ect).
also need to know what shocks your running
the front end of my truck with a fabtech 8" lift has been lowered to the point my CV's are always level along with the tie rods. that said, i have no bump stops for the LCA in the way and i run a coil over. you wanna talk about a smooth ride but i have 50% up travel and 50% down travel at ride height. that means i have 6" of wheel travel till i bottom something out and 6" of down travel till my suspension is limited (this is alot more wheel travel than you will have). when you lower a truck like your doing, all these limiters change in the amount of clearance you may have and dependent on the roads you drive and how your drive, this can make the ride worse. This is why a cranked up truck on stock UCA can ride like crap too. you loosing suspension travel in one direction over the other.
