I also had a pair of Spyres that were underwhelming so I went to these. They did work better but I didn't like the amount of ongoing maintenance they require (I like doing everything myself and the bleeding is just such a waste of time). So I went back to mechanical discs, and the only one I've ever been impressed with are Avid BB7s which I now have two pairs of. Hope that's useful.
