Wish i went pin down. I have 4x4x2 pin up and leave nothing but 10 pins with the Fight. Have tried changing surface multiple times. Same result. No confidence in this ball. I should have it figured out after 2 months. Might be time to move on. I was hoping Fight would replace my aging IQ Tour but no chance of that happening. Might have to buy a 2nd IQ Tour. Going to Reno soon and shot is tough enough with a ball you have confidence with. Can't imagine using a ball that you have no confidence in. Last resort might be to plug Fight and drill it pin down.
