I shipped some Srixon AD333 to the US and I find them to be fantastic but can’t always find deals. Srixon balls are made at different plants depending on the ball… personally I find the Q-Star Tour balls to be poorly made… you can often feel air pockets and then watch them tumble through the air. Can’t imagine they help your putting. That said, love most Srixon balls. XV, Z, AD333 and even find the Soft Feel adequate in a pinch. Long, Don’t roll on approach shots and are easy to see.
