Virtual Pool 4 - 9 Ball World Championship - Preparation

Hi Guys, Just some pre warm up before the World Championship 9 Ball in Virtual Pool 4. I started off with testing the break and come up with several different breaks... In the end I stayed with one break which seems to be consistent with potting, who knows... the break I feel is quite random to be fair, specially in VP4. Any suggestions on what I could practice with?
