Thanks for the nice comments, yes smoothing the CG is next on my list. It's actually a replacement from Josh since I managed to wreck the first one;
Don't do this if the lever is loose... drill a hole in the lever and try fit a rubber tube around the lever pin (Jimmyzfu style), if you are clumsy like me
Just do this, put a thicker o-ring under the crown and some soft setting glue around the pin in the lever, then everything's fine
Oh, and the palp crown is not the sandblasted "Ti" crown from Palp, it's actually the polished Palp crown that's been brushed, repeatedly heated and cooled w/ a gas lighter to darken it (and then washed of course).
