Out of curiosity, I conducted a simple polyester voile strength test.
The bag, poly voile machine triple stitched w/ tight zig-zag type stitch...

The weight, 67 lbs of dumbbells, 2 - 20's, 1 - 15, and 2 - 6's...67 lbs total
The strap tied off to the top of the bag, this is an inexpensive HF lashing strap, it works quite well to suspend the bag from a ceiling hook. I prefer this method as it spreads the load over the entire bag, as opposed to stitched handles or attachment points on the bag.
A short length of cord or rope can also be easily wrapped and tied around the top of the bag for lifting and will cinch the bag very well for even heavy duty lifting.
The test, bag took the weight w/ no issues...none whatsoever!
I have done BIAB grain bills close to 40 lbs, and have always surmised the poly voile could handle more weight, I would also imagine the irregular shaped dumbbells put much more stress on a bag than the even loading of a mash. Also interesting to note that I believe a grain bill of x pounds, weighs less than x after conversion and water absorption, so a 20 lb grain bill weighs less than 20 lbs after being lifted out of the kettle.
Myths busted:
1. BIAB is not viable for larger batch brewing.
2. The use of a strainer basket is needed to support the bag.
3. Handles are needed on a BIAB bag for large grain bills.
Thanks for watching this experiment...cheers!
