What bowling ball should I buy for heavy oil lanes?

Hi, I have been bowling for 2 years now and I have a 180 average. I usually figure out what bowling ball I should buy myself but I don't know which ball I should get this time. I am looking for a bowling ball that is heavy oil because I am going to a JBT in Las Vegas this summer and I have a feeling the lanes are going to be heavy oil to make it a challenge to win. So, what is the best heavy oil bowling ball I can buy?What bowling ball should I buy for heavy oil lanes?

As you can see, there are tons to choose from, but basically ask your local pro shop to see which one matches up best with your game. Also, check the ball manufacturer websites or bowling.com, bowlersparadise.com, bowlingball.com or bowlingballsales.com for further info. Hope this helps!
