All good points. I am also just thinking, deciding etc. One thing that is less of a problem for me is removal - I don't plan to ever remove it With current setup I open the front panel of the windshield (window if you will), thats it. I certainly don't remove the top - I like the shade (and its also somewhat a requirement - gotta hide from the sun). The guy that does the work suggested macrolon and I liked the idea but it is pretty expensive, so I am not sure - this project is Big Money as it is.

I did look up some of these rope track connectors. They have a connector like that for the edge of the hard top, pre-made and very sturdy. I guess something has to be improvised for the inner surface but it's an idea.
