Even though those needles are called big eye I don't think they are. I use Roxanne needles and have no problem getting a 30 wt quilting thread through the eye. I usually run my thread through bees wax and a great tip I got here was to moisten the eye end of your needle instead of the end of your thread. It works great. I also have a magnifyer glass on my Ott light which I have to use. I do not use needle threaders.
Try the Roxann needles, I think you will really like them and they really are a lot easier to thread with heavier quilting thread.
