Ground level view of PROPUCK in action on a rough outdoor surface. Large flat glide pegs displace a great amount of surface area relative to the puck's overall mass. Vulcanized rubber construction provides unsurpassed dampening of vibration as it travels the course. PROPUCK stays flat as shown, negotiating cracks and divots that are inherent on common outdoor surfaces. Identical view of a plastic puck traveling the same path, on the same surface. This plastic puck's glide pegs displace very little surface area relative to its overall mass. Hard plastic makeup provides insufficient shock absorbtion for rough outdoor surfaces. Tiny round glide pegs snag in cracks and divots, causing the puck to vibrate and pop up on edge as indicated by the arrows shown.
Ground level view of PROPUCK touching down on a perfectly smooth surface of play at a 25 degree angle. At point of contact this puck's glide pegs provide initial & continuous frictional resistance as the puck travels in it's natural rotating motion. The glide pegs provide 360 degree frictional reduction along the peripheral edge of the puck, where it is desperately needed in this instance. Since the plastic puck's glide pegs do not make contact with the ground, they are useless for reducing friction. Fact is, this puck was not designed to address frictional resistance when propelled from horizontal as shown where puck body , not glide pegs, make first contact upon the playing surace.

Ground level view of PROPUCK on edge, 85 degrees from horizontal to perfectly smooth floor. Hit the side of the rolling puck, at this postion runners engage surface, reducing friction where it is needed. Follow through with stick and puck falls flat to the floor quickly, and easily for greater control.

 Identical view of plastic puck on same surface of play, all conditions being the same. When puck is struck to this position, glide pegs are nowhere near the playing surface. The puck continues to roll without the aid of a friction reducing means along its edge. The player has more trouble getting this puck to lay flat.
