ProLine is DGA’s grippy premium blend. Opaque with a little translucence, tougher than the baseline lines, softer in the hand than SP.
That makes it the everyday premium choice across the DGA range, with fourteen moulds listed. It’s the class of plastic that holds flight through a season and keeps its grip when the disc is wet.
SP outlasts it. If a mould’s flight is the thing you want to keep for years, ProLine is the second-most durable option, not the first.
