If you actually want it to ride nice, I don't think there's any other option. I would say especially if you already need springs, it's certainly worth the extra money. (But even used springs in decent shape can sell for something decent.) I started out with Rough Country front springs, but eventually got sick of the bouncing and upgraded to Tuff Country EZ rides, which were noticeably better. And this is considered the best-riding off-the-shelf spring for our trucks. The flex was also pretty respecatble. However, the truck still wanted to "hop up" on every bump. I came to realize that stock pickups rode much better on 2-tracks than my modified rig. The problem became even more apparent in my "overlanding" runs, where I was taking a beating trying to keep up with almost stock Land Cruisers, Rovers and the like on lengthy forest roads. Eventually I took the plunge by calling ORD, and also upgrading to Bilstein 5150s, and I have to say that it's an entirely different truck. Now other solid axle rigs ask me to slow down. The ride around town is downright pleasant. It's like they fixed every road in my area overnight. I don't even swerve around the asphalt patches anymore because they aren't that noticeable. Any 4-wheeling I do is much easier and more stable. Basically the suspension works like you imagine it should work.
You have to question how the lift kit manufacturers can sell the same spring for every square nose, whether 1/2-ton, 3/4, small block, big block, from K5 to K20 Suburban and they all end up at the same height. I think it's OK for an unloaded 1-ton to ride like a 1-ton, but I don't ever plan to carry 2000lbs of gravel on the front of my K5, so why have all that spring rate?
There, that was my soapbox speech - as advertised :-)
