I used one for the first time yesterday in a county twos trial game and they must be the hardest ball I've ever played with. The one used was a kookaburra and a few of the lads like jack manuel who plays a bit for Worcestershire 1s said there horrible to ball with, He was right! They don't shine up and don't swing much! Definitely a batsman friendly ball as after 60 overs the ball was still rock hard and going to the boundary! Nevertheless an interesting and enjoyable experience!
