I've owned 3 TJs since '97. 2nd one I had to have the dual top for the hard top. I never used it and was a pain to store, I bought a hoist and all too, was a pain to switch back/forth between the tops. My '06's soft top is quiet, plenty warm, even with the -40 F record temps we had here in the last few winters. It's been awesome. If I did a ton of highway driving, maybe the hard top would be a better choice for less noise. Then again, if I did that much highway, I'd have another vehicle better for highway.
