spot on Dell, the 1x collie grey to a salukix grey or a deehoundx grey, make very good lurchers. The 1x colliexgrey is the start of your lurcher line i think for edible game. But you do get some fast 1x collie greys, i have one With Bryn. He is fast for a 1x collie grey not a daytime hare, but in the lamp will catch any edible quarry.
