I don't have anything to offer, except my hard/soft top experiences. I had a vinyl top from Beachwood Canvas. It was pretty well shot after 5 years parked outside. Was getting a little crusty then the squirrels started eating it. (I've heard Beachwood is out of business, but their website is still up.)
I have seen one of the Boyce fiberglass tops in person, and they are really nice. Not sure I'd put 1500 in one. They are still listed on the Boyce site.
When I got it, my truck had a "forest service" style top riveted/welded to the stock soft top bows, windshield frame, and back of the cab. I cut it off, and tried to save it, but between being in the way for too many years, and what it would take to make it usable again, it went to the scrapyard. I did like it though, and if I could have made that one removable, I would have happily kept it and used it. One day I'll build a new forest service style top for it.
Tim Barr's video has a good view of the forest-service design fabricated hard top: (you can see the underside at 1:00, and the exterior starting about 8:45)
