I use a Sharps #9 (bought a package of 20 off Joann's notion wall) and I am using Coats & Clark Dual Duty Thread for my scrappy 1" Hexie quilt. I have thread basted I can't tell you how many hexies and I have joined together 1,260 of the hexies and I have not had a single problem with thread tangling or shredding and my stitches do not show on the front. I sew with a piece of thread no longer than 18" and take a small whip stitch that only grabs the edge of the fabric. Sorry you are having so many troubles.
ETA: I just checked the needle packaging and they are Dritz brand.
