I have all the colors of their Essential Pro thread and use it on the LA when I need the color. I have a few of the cotton but bought them before EP came out. I never use it(for anything) but not for any particular reason except it's not poly and on a cone and that's mainly what I use; especially on the LA. I do remember when I first discovered CT's thread I especially liked the color called kiwi and used it on the LA without a problem. Back when I first stated using the EP I was disappointed in their lack of colors(and still am even though they have about 30). I use a variety of threads, and I mean a variety, and almost all of it is poly except for King Tut and a few others, and as I move forward in my quilting journey I find myself using less and less by CT. And their price is definitely right but I haven't bought any in more than 2 years. I can see myself in the near future using EP for piecing just to use it up.
