Eternal is Mint’s premium clear plastic, moulded by Prodigy, and the Mint blend to compare with Innova Champion and Latitude Opto. Clear, tough, and slow to change. Ten moulds are listed in it.
That’s the plastic for keeping a mould’s flight and for hitting trees.
Grip is the trade: slick when wet, stiff in the cold. APEX is the Mint blend for feel.
