Most recent regret? The Bestop Nextop NX!!!
Not the top itself so much, but the fact that I tried to install it on the day the first cold snap rolled through. Got about 1/2 way along the install and it got cloudy, windy, and the temp dropped into the 30s as the sun went down. I gave up. There's about 2" of gap on each corner. The top is now generally draped over the Jeep. Maybe this weekend.
I did the same thing with my top last winter. I almost destroyed it trying to get it on. And especially the half door tops. I had to literally soak them in hot water in the bathtub to get them to stretch onto the frames. My soft top I had to put it off a month or so. Until the weather heated up. But once there was a hot day and direct warm sunlight on the top. It went on.
I don't know about the Nextop. But if it requires the frame. Make sure you keep the foam on it. Or add some later when your done. Made a big difference in my top recently. As I had removed the foam to install the top. Stupid idea.
I think you'll like the soft top. BUt wait until it rains to get rid of your hard top. Just to make sure the soft top doesn't have any leaks anywhere. If it rains alot where your at. It may be an issue.
