Sunny is Clash’s stiffer premium blend, made for hot weather and hard throws. Same opaque grip class as Steady, with more torque resistance.
That makes it the summer plastic, and the one for players who find Steady flexes too much on a full-power drive. It holds its shape when the temperature climbs.
In the cold it’s going to feel harder still. Only two Clash moulds are listed in it, so most of the range is Steady whether you’d prefer Sunny or not.
