34mm is the correct size for this mouse.  It's the same size as the stock ball.  Considering this question is a month old, you probably already found out.

I have had this issue and found that dust builds up on the pins that the ball sits on and makes it roll hard and jumpy. Take the ball out and clean the pins.
