I have half doors with 6 year old, clouded Smittybilt brand soft uppers velcroed onto what I believe are OEM frames, and I have a set of full doors that the LJ came with. Full doors have been off for almost a year, currently taking up space in the attic. I did completely fine driving it in cold weather over the winter, and for the rare occasions I have all the windows on in summer, they do well enough to stay comfortable with the AC on.
...but as we've discussed, they're noisy as hell, and road trips of any length I'm wearing earplugs and cranking my stereo to hear through the plugs. If the bulldawg fiberglass ones were anywhere close to full doors in sound level, or at least quiet enough that I could drive for 5 hours without cranking up my tinnitus, I could feel ok with selling the full doors and just use the hard uppers for longer road trips, and build a storage rack to store them in the Jeep so I can take them off and keep them from getting beat up when I get to my destination and go wheel.
