I would say that a working staffs are rarer than a well bred pit these days . When I first started out lamping in the early 90's I had collie xs and deerhound xs . I had a range of different xs when I was younger and most was good pot fillers . Then 10year bck I started with bull xs and I had my fair amount of shit ones but never let it put me of them cos when you have a good one then there worth there weight in gold . There just as bideble as any other x of lurcher . But it depends on what bull people are useing if it's not a apbt in the x then your gonna struggle as there is only a hand full
