Both: Hammer built it for medium to heavy oil and transition. The polished HK22 Cohesion Pearl pushes through the heads and saves its energy for the pins, so it is the Black Widow to move to when the solids start reading too early on a drying lane. Leave it polished for length and angle, or have your pro shop take the surface down for an earlier, smoother read on more oil.
