Fastbreaks and dunks are the only decent cupsoles made for skating these days IMO, i havent tried those adidas forums, but they look like they would be good too. To be fair, i havent tried any of the DC's, but im a high top guy and they look WAY too bulky anyway.
TBH if you're looking for cupsoles, look at non skate shoe brands and buy some superglue. It's fun finding old/used stuff and skating in it (if it looks like it will skate well). You might be surprised how good some non skate shoes are to skate. Reebok and Asics both make shoes i've really enjoyed skating in.
