The 18oz vinyl is a lot lighter than the original tops... or compared to a stiff old top.

I haven't had the full top out for a run yet, as I need to add a tensioner for the front top in this configuration ( remember, my front canvas is not anchored at the rear, and is fully removable). When I did the front top years ago, Rick at Mauritzon steered me to the 18oz because of the flexibility ( also the only weigh with the color I wanted). At the Parker Treffen, a 1" branch had jammed into the front right corner of the top, the branch broke off and folded a corner of the top back, upon inspection, that was all it did... fold the top back, so I folded the top back into place, and never gave it a second thought.
The point of concealing the cord inside the vinyl wasn't because of them catching on anything, but to get rid of the extra hardware and make a cleaner looking exterior. There are several variations of tops that were made for 716 and 718s where the cords are internal. I am also finding out that the tops are easier to handle without the shock cords and hangers dangling everywhere.
