Just took the shine back off of mine. I have one pin up (pic in profile) that before the polish was good on med/slightly heavy. It gets good length and is pretty angular. With the polish it turned to a med light oil ball. Just kept going and broke late. If I were better at straighter angles it could've worked, but for now I need the 4k sanded and keep working on those straighter angles.

I am thinking of taking it down to 1000 then either using Step 2 or Reacta Shine.  I am looking for it to have decent skid with a strong angular move on the back end.  My biggest problem right now is patterns that the heads get burnt up but there is carry down.  Of my current arsenal I can either get the ball through the heads with minimal back end, or use a ball that will move on the back end in carry down but have a hard time getting through the heads.

A friend put Finesse-it II by hand over the stock 4000 grit surface, using a 5"/5.5" pin above the middle finger. He uses it on our medium-light oiled Thursday night league to very good effect.
