Got mine January last year. Drill pin above ring finger. Hate it at first, very uncontrollable.
I decided to take to polish off with 800 grit sand. Polish again with Powerhouse factory polish. WOW! It's like a difference ball. I found it good with medium oil with a clean or spotty backend. It could handle a bit of carry down but if too much it wouldn't move. I've to open up a bit for the ball to have full potential. Mostly is from 15 to 10 and it came back strong.
Hope this help.
