Thanks for the quick replies. I've already swapped out the cord but it just seems silly to have the monster grossgrain tieouts. I have made tarps twice the size with 1/2" grossgrain with no problems.
I cant see why it would be more expensive to use lighter cord, locks, and tieouts. It wouldn't need to be anything high tech, just smaller.
Heck it may be cheaper depending on what was used.
