It’s a different style of ferreting here mate, in most places for most of the year we can’t dig, so I opt for smaller bucks and Jill’s, the rabbits can pull away from them in tight spots most of the time , also I won’t keep a ferret that stays with the kill. The bigger, stronger, faster ferrets , just catch too many underground, only down side is the smaller ones usually don’t have the stamina of the bigger ones, 2 Jill’s weigh about the same as a big buck ,just means I carry a couple extra. Horses for courses
