The Storm DNA Coil is one of the HOTTEST balls on the market today. I drilled mine 5.5 x 5 x 5 and after the first time I threw this ball I knew it was going to be a huge success! For a pearl it is very continuous off the end of the pattern but still gets down the lane with ease and always just seems to strike. I have a few sets over 840 with this ball already and it’s been my go to piece when ever I bowl!
