IMO -- I believe that the Hyper Cell will be a better ball for conditions that have heavier head oil, because that ball will burn up when their isn't enough and leave flat 10's (at least for me it does) --- I don't believe the Lock will burn up as much, but I am not sure yet. I am speculating. The Hyper Cell compared to the Lock does not have as much of back end movement as the Lock does for me. This could differ with lane conditions and rev rate. Comparing it to the Critical, IMO -- the Critical gets down the lane further than the Lock. The Critical was a pearl, the Lock is a hybrid. The Lock gets into a roll earlier in the the midlane, but both have strong backend movements.
