I have problems with connecting threads thread breaking too. I can use it for piecing but quilting is too much trouble. Unfortunately I bought about 2 dozen spools of it. I started using Wonderfil Konfetti and love it but the LQS won't be getting any more until they pay their bill (whole 'nother rant about why they told me that) and it's not that easy to find. So I think I'm switching to Aurifil. I can get it from j hittle for a decent price.
