I've never used Paton's either. I have looked at it. The last I looked - and touched, most of it felt pretty scratchy to me. but one color - not the color I was looking for - was really soft. One of those things that make you go 'Hmmmm . . . ?'
I love Patons Classic, but I could never knit a sweater with it. I've heard that since it does felt extremely well the slightest bit of heat+moisture+aggitation will felt it. In other words, if your underarms get sweaty you're going to have felted pits which is a bummer when you've spent hours knitting a sweater. I only use sythetic wool blends or superwash wool for garments, but Patons is excellent for other projects - especially ones that require felting. IMHO it felts so much better than Lion Wool.
