well i use mine for all rounders, ime not bothered what size fields i run them in, big or little no "excuses" and it doesnt matter how rough it is, (cos they are fast enough, up and at them type,) or how flinty or stony it is, they are "capable" of taking a far wider range of quarry than you actually mentioned, they work on the lamp, mark rabbits and rats etc, they work with ferrets and falcons, will swim rivers, jump anything, mine will go through bramble bushes nettles allsorts nothing bothers them, they live outside the cold doesnt bother mine one bit, they never shiver, they are quiet and
