Which specialty threads do you have problems with? I use it with bottom line, rayon threads, water soluble threads, just about everything I sew with. I think I did have trouble with a really stiff nylon monofilament (I don't use that anymore) but mine worked with a better quality rayon monofilament. Mine is a Bernina 440QE.
