I like Wonderfil. I was given a sample pack of it and it's great thread. I use the 80 wt for hexies. I have and use lot of Aurifil but no so much pleased with the last few spools I bought. Just seems different to me from the older version. I try to not overthink thread. I go by how my machine sounds when it sews. Different brands sound different. Silly but true for my machine. Right now I am using Missouri Star cotton thread and poly and it is sewing perfectly with no issues.
