Yes, I use it.
I use it when their posted line is not as good as a line at other site. I then compare what kind of additional juice I would have to pay at Pinnacle if I used the better line. In some instances, I can get the better line at Pinnacle with additional juice. In some instances, the line at the other site is better than Pinnacle's same line using the Dynamic Lines becuase the juice is lower at the other site.
Therefore, using Pinnacle's Dynamic Lines, I feel I can get the lowest price on a specific line.
I hope I made the above clear.
