I am coming around to agreeing with you on the poly. I have made quite a few with each, and have recently noticed that baby quilts made with W&N cotton (especially the flannel ones) tend to look tired after several washings. Poly just seems to hold its shape better. I also agree that the plumper look is richer, especially in flannel, and when you are making larger quilts, the poly tends to seem lighter, yet still warm.
