That's where I bought mine too. I went upstairs yesterday to tug on a variety of threads after this discussion and of the ones I tugged on, Aurifil 50wt definitely broke with the lightest pressure. I even tried a couple different spools of it, cones and medium spools with the orange spindle.
Connecting Threads 50wt broke with a little more pressure than the Aurifil.
It was much harder to break the poly serger cone thread that I bought as a newbie (not knowing you're not supposed to piece/quilt with that!) so I feel better about having made several quilts with it! I had to pull a couple of times to figure out how much pressure to use. It finally stretched a ton before it snapped.
I couldn't break the Coats and Clark machine quilting 30wt thread that I used to buy before I knew anything about weights of thread. It actually hurt my hand a little.
