SP is DGA’s premium clear plastic and its most durable blend. It’s the DGA equivalent of Innova Champion: glassy, stiff, and slow to wear.
That’s the plastic for keeping a mould’s flight. Eleven DGA moulds are listed in it, mostly drivers and mids where flight retention matters most.
The trade is the usual one for clear plastics. Grip is the weakest in the DGA range, especially wet, and it goes stiff in the cold. Reach for ProLine if feel matters more than lifespan.
