What lines ????
ones that are doing the job on that sort of land, Romeo for example put back to smaller fast type bitch would likely produce something your after, seen a Dickinson bred one my pal had was perfect for that sort of running, look for smallest in litter maybe, by rule of thumb a real good un will kill anywhere, think if hare the main quarry you better off with this sort cos they will soak up the hack of repeated runs, and should never really be overfaced on smaller land when hares at there best, cos thy either gunna catch em or they gunna be goneCheers artic
