If you look to grab Sulky Blendables, be aware that there are several weights -- the smaller the number the thicker the thread. If you use 12 weight on top you will need to lighten the tension and use a 100 or 110 needle. I love using the thicker threads since if I am going to go to the trouble of quilting something I want it to show up.
Every machine has its quirks. My 35 yr old Elna will sew fine with any thread any weight -- including wooly nylon. My previous machine hated all varieties of Sulky, but would sew just about anything else. My current machine is OK with Sulky, but has fewer problems with poly and rayon than with cotton (any brand).
For piecing, I frequently use titanium needles, but I have to watch what thread I use. For quilting, I use the Metallic needles as default, but if I don't have them the top stitch or jeans needles work as well (for years Jeans 90 was my default quilting needle).
My advise is stitch a sample and see what works best.
