I’m trying to make that same decision. I only planning on swapping on the soft top for the summer so maybe I can get away with the black diamond, but my gut is telling me to cough up the extra dough and get the higher quality one.
For what it’s worth in every thread I found about the subject on the Jeep forums most people seem to think it’s well worth the extra money for the higher quality material.
It’s quality stuff. Only downside is it might be harder to intially put on. I just installed my trektop today and you really have to fight the windows to get them to snap in place. Because the twill is a much sturdier product it might make it much harder to stretch the windows into place
Also if you do get the trektop listen to everyone’s suggestion and get new hardware from ace or something. I just barely managed to wrench them on in some places without stripping them. Makes me rethink seasonal hard top
