I going to drill one tomorrow, I haven't had the greatest of luck with brunswick Asymmetric balls as of late. My Ultra was 45x5 1/2x70 and it was very rolly and did not like to be thrown away from the pocket. My Wild is 60x4 1/2x40 and its hit or miss, it seems to need a lot of friction early to be affective. So those who have experience with this core I am looking for suggestions, my specs are in my prof. I am looking for something to open up the lane, I have good luck with pin down balls because I like to throw it hard so I am thinking 60x5 1/2x70.
