I've seen both, and the madstad too.
The slingshade looks great. It is the only top that doesn't make the rig look like a dune buggy - to me. True, the top panels are floppy, which I found disappointing. And, they are not removable. But, they are ABS, and should outlast the life of the owner. And, the rest of the frame is seriously sturdy.
@av8ingtom has not removed his panels yet, but if he keeps on driving off with a panel flipped up, it will self remove sooner or later. We had to flag him down at least twice last encounter. Hi Tom! Bring a See-Gar for me too next time!
Yes, someone needs to be behind him to pick up the parts!
