On my old black TJ the Currie 4" lift settled in near perfect. It rode excellent, and it wasn't noticeably higher in the front or back, it was about even all around. I'm putting the Currie 4" springs on my new TJ with the Savvy mid-arm lift and outboard shocks this week, so we'll see how it goes the second time around!
I've played this game too. And I'm sure Blaine remembers some of it and was kind enough to suffer through my experiments. While I was able to tell the differences between certain springs on my daily driver on the same roads, I also eventually realized that changing shocks and tire pressures made far more dramatic differences by comparison. And I didn't need to focus to find those differences. Our efforts in ride quality belong with the shocks.
