i would agree ith the above. but would add that the faster dogs cant look at the ground i run my dog on. they gain in pace but lose on durability. a good first cross is bred to work all terrain all weather.
Total agree fellah, But where i am in the midlands big open land with thin hedges need a dog with a decent turn of foot and seen the them lack slightly here like you say diffrenet terrain suit diffrent X's
agree'd
