I love poly thread for quilting and use it almost exclusively in my LA. I prefer the look of a shiny thread and I do get a lot of lint with cotton. This is more of a problem with LA than DSM because they work at much higher speeds than a DSM. I don't shun cotton, I will use it if the color is just right and I adore experimenting with threads. So I do use many different fibers and weights. It all depends what I am doing and what look I am going for. It is not uncommon for me to use several different types and weights of threads on a single quilt. I would suggest you explore all your options when it comes to thread.
