Surface: To take a step further, and take you to a new world of finishes, I present to you, Deus Sententia. Fresh from the space labs, this is a low-friction, durable finish that is a true dream for anyone who enjoys grinds, thumb grinds, or who simply enjoys the feel of a yoyo that is silky smooth.
Spacers: A new yoyo is not complete without new technology. The phi utilizes a new concept that eliminates the need for clumsy ASG systems, tiny spacers that are always missing, and extra parts that you have nowhere to store. Simply flip the spacers over, and you change your gap setting, and how the yoyo responds. No more squinting into the light to twist your yoyo just tight enough, no more re-adjusting every time you get a snag, simply set it to 1 of 3 positions, and leave it alone.
Response: A yoyo is not a yoyo unless it goes both down, and comes back up. Down is the easy part, to bring it back; the natural choice seemed to be Carbon Fibre Pads. They are durable, wear very slowly, are remarkably smooth, and will insure a tight wind and a solid throw every time.
Bearing: As with any modern yoyo design, a ball bearing is used to allow for long spins, smooth tricks, and phenomenal playing abilities. A large bearing is used to allow for the maximum gap size, while still maintaining a good feel.
