I drilled my HALO PEARL up 65x5x35 which is my standard layout for large core asymmetric balls.
I left it box since I have only had a chance to throw it on house and a sport pattern that is 45' and it rolls even on that long sport pattern. This is a great RG pearl like the NO RULES PEARL and CELL PEARL which seemed to never miss the spot downlane. I have been able to throw the HALO PEARL like the other two above on the longer pattern and it holds a lot of energy. It also gives me some good indications when to move out of a zone as it will go forward when it burns too much at the break point. It might still carry the shot, but it is time to go left even more at that point. I will post when I drill a second one to put some surface on as the NO RULES PEARL and CELL PEARL were excellent balls with surface also.
