Yep. That's who I use for wool batting too. Big thumbs up.
I've tried their roving tho and didn't care for it. I think it may be a super wash because it takes some work to get a good felting. For plain roving, I get NZ corriedale from the the copper moose at ebay. Soft, super white and fluffy. Twice the price but 1/3 the labor. Great felt.
eta:
I just wanted to clarify that all of the roving I get is ultimately wet felted. So for needle felting, the roving from them would be fine.
