Linebreeding and inbreeding are both practices that most breeders use to set type. It is the surest way to pass on good qualities to the foal.
I have bred a half sister to my stallion with very good results. You must make sure both individuals are correct and without major flaws.
My Stallion Star is related to everyone of my except one . I line breed to Bask and to Ruminaji Ali.
The Babson arabians are all descended from 1 stallion and 4 mares imported into this country in the 1930s.
I think there will be no problems with the cross. Shalom
