I'm really a novice quilter, so this might not be applicable to your problem. I tried to use the
Coats Transparent thread to zig-zag around a Dresden plate block and did not like the result. It stretched and mangled the block. So, I removed it and went another route.
Later on, I bought
Gutermann Invisible for quilting a multicolored I spy quilt with a walking foot on my domestic machine. I matched the bobbin thread (just regular thread) to the backing and used the Gutermann in the top thread. It worked perfectly. I would do it again.

edit: The Gutermann has a little texture to it and the Coats is very slick, which may account for the difference in handling. Neither spool has any kind of weight or measurement on it regarding it's thickness, but the Coats feels smaller, but it could be the texture component that makes it feel that way.
