I have a 3.5 and it would roll out. I would have weak pocket hits. Just for the hell of it I sanded to 4000 and polish the crap out of it. What a change for the better I was ready to sell or donate it but I will be keeping it now.
I have had some good success with it just need to put in the bag by the 3rd game still a strong ball for me, but i like it now.
