I am with you the blacks pits are what started it off for me. My very first Pit was an all black GAMED out 40lb killer. I miss my girl con chola, I got her in 1984. All my pits were 90-100% solid black until my first semi bully breed pit in 1998. My goal is to bring back a solid black strain.. With the help and collaborations with a bully named Mambo-G(Meathead/cali swagger crew) I think I might have it on locks!!
