what are d' strengths of ursus and qauntum lines? - Page 1

just wondering what are the strengths and weaknesses of ursus von batu line and quantum arminius lines? are their any specific characteristics that i should look at when looking at dogs with the two of them at the pedigree(2nd or 1st gen dogs). i have a gsd who is a 2nd gen ulk v arlett son. the breeder told me that ulk arlett progenies are typically medium size and super movers, and true to what he said i really got the dog that he told me. on the other hand he also told me that hes not going to have the really huge head some lines have. thanks for the info
