I have both the Blaze and Power Charge and agree with the replies so far. My Blaze coverstock craves a little more attention than the Power Charge. Blaze is more skid/snap and the Power Charge is one hard-arcing ball. When it begins its move to the pocket, it doesn't stop. An easy ball to adjust to lane conditions. The Blaze is a little more condition specific, but hand position and speed makes it adjustable to different conditions. I have noticed that the Blaze skids slightly on carrydown when swung out a little, but the cadmium particles in the coverstock will tend to hold and cut through that same carrydown if the ball is already making the move toward the pocket.
