I'll be interested to hear your review. Hope it works out for you. Please report back good/bad/indifferent. I think the sale price is worth at least trying it.
I know some people mention being surprised by the (small) size of the spools, many mentioning they are smaller than the people thought, but there is also no spool to speak of, so the spools are 550 yards, while the Dual Duty spools are 400. The cones of the same thread are 10x as much yards! I will warn you that the box they come in is also smaller than I expected.
