Jills all the way if you are using nets, if you are using guns or dogs then hobs are just as good, downside with hobs is that they are heavier so have more tendancies to make a kill and lie up for a few hours kip, not a good idea to enter them hungry, although don't feed them too much before working them or they will be less effective, they still need some food in their system for enery while working. Hobs are also excellent for ratting when you are ratting in sheds where hole size is not an issue.
