Halo Pearl wow what a ball,just by taking the original halo core and wrapping it in a pearl cover makes a big difference alot more skid and alot more backend.Drilled mine 60x4x40,a ball I can go to after my halo is a little early and burning up when the fronts go,i can take my halo pearl and stand in same place and play same part of lane with ease.Looks great going down lane and has great colour combo.I wouldn't use this ball if lanes are burnt up that bad thow be way to much ball,for sure after a couple games in league or tournament play can go from halo to halo pearl.Also great for house shot and sport shot conditions.
