Yes the Engetsu I have 4+1 bearings is quite smooth as of now. I'm guessing you swapped to a bushing because the bearing gets a touch of water and becomes rough feeling? I say this because my curado I got that way and had to replace the bearing (I used ceramic bearing for its better protection from moisture that a great friend provided) I tried repacking the old bearing with grease but I guess the balls we're too far gone (using a sharp hook to open the bearing)
