Well, i'm running one right now with a KMC 415h chain and a profile 36t blackjack sprocket, and I love it. If you dont' liek that super loud clicking though than this isn't the freewheel for you, i like it though cause riding in the city people here me coming haha, almost reminds me of having some basebal cards in the spokes.
Overall very solid piece though, I got mine after meeting osmeone who swore by it and has had his for several years.
check out some reviews of it on www.bmx-test.com
they have freewheels under Misc i believe.
