thanks mate what would you suggest ? someone told me a whippet x greyhound
To be honest mate, once you get onto lurchers it's just what pleases you.
Now if i was you, looking for what you are, where you are. . .
I would find out who had some belting rabbiting dogs, and look for a pup that was bred out of two dogs that did exactly what i wanted my pup to do, and that i quite liked the look / feel of.
I'd be way more concerned with finding the above than any particular breed.
Having said that, i do think if killing bunnies is your thing, you'll be hard pressed to fault
