I only use Jills these days, I find I get less lay ups,and if a rabbits intention is to escape, they can still drag a Jill to the net, the down side is usually they have less stamina so you need to carry more ferrets (that being said Jill are lighter so it evens out almost) its horses for courses but that’s my opinion. both are friendly if well handled, I use a vasectomised hob to bring them out of season, if I want to breed a particular line I use a friends hob.
