I bought one used around 5 months ago. Tonight I decided to clean it up and lube it (as well as tighten some shit down). FUCK, I get why these are popular. Shit is fucking smooth as hell, especially lubed and tightened up (actually that was why I did it, it was noisy). So much better now though haha. CSB of course. The only noise I could not eliminate was the spring flexing. I have no idea how to fix it other than replacing it so I guess I'm just gonna do that.
