I have the HQ and I can use any thread. You do have to experiment at times.
If you get a lot of thread breakage, try loosening the needle tension. If it is still happening, only go thru the top 2 holes in the pretensioner. If it is still happening try using a larger needle.
I really like using the SUPER BOB'S by Superior for my bobbins. I get good stitch definition and very few bobbin tension problems with them.
Have fun with the new machine, I absolutely love mine.
