Anybody using this kit had issues with the airecore drawstring on the cuben bag cutting or ripping the cuben bag?

The drawstring can hold my fourteen pounds of food, but when I hoist the bag up it looks like it may, over a short time, rip or tear the cuben bag up.

Anybody used a wider diameter drawstring instead?

Okay, I'll answer my own question...I was out for a week and had 14 lbs of food and it held up without any cutting or ripping!
