I don't specifically have T47 but I have Kactus, DJC components (BSA 68MM) and both of them have been fantastic. Both claim to have ceramic bearings. On the more expensive side, Token Ninja. I have their thread together BB386 bracket on VB GF002 but they make T47 too. No creaks, spins smoothly. If I ever get another PF frame, I'll get Token Ninja again without doubt.
