I like to put my hob a nd jll down a the same time obviously give the jill a few minutes then him it works and she will always be much faster than him ..it was last week i was digging down to my hob and i got a mark of 4 on his and 2 on hers thought a shes only going back through it but turned out she had one dead in a stop end and another backed up and he then had one dead in a tube ...but i do find hobs more thorough and will stick at the bunnys till they move or they kill em
