Action, I am wondering too how well it will work in practical use. The securing straps of velcro that go around the tubes are currently able to flex and roll as they wish because the foam is not glued in place, which is different from how the standard soft top foam is fixed. It may well be that the foam has to be glued down. I'm holding off so that I can see what the whole mess rolls up to, with and without foam, to see if I will have to ship it without the foam (which is readily available and cheap anyway) so that it comes in under the FedEx/UPS large package penalty.
I'm independently worried that it will be a floppy mess, which has already been raised. Time will tell, and soon.
Still, it's coming together very close to the picture in my head, and I am pleased so far. I will definitely make several minor changes to the patterns, and sew it together in a different order of assembly, having tested the patterns and learned as I went.
With some hard work tonight I should be able to mount it in time for the rally tomorrow to show to others and get their feedback (and pre-orders, of course
.
