This dual-sided practice pad features surfaces that are softer and thicker in nature than most practice pads on the market. The ¾ inch Flexx surface works well for all types of techniques and velocities, including those utilizing the arm, wrist, and fingers. The other side features a oe inch Workk surface, which offers less bounce overall, though still provides a firmness allowing for strokes to be more audible than on a pillow or other completely dead surface. The Workk surface is a good place to practice techniques that involve the upper and lower arm, and wrist specific movements that utilize a larger range of motion, at low to medium velocities. Ideal for drummers looking to advance their technique, this practice pad promotes control, strength, sensitivity, and endurance while allowing for a greater range of stroke velocity.
