You can't tell line from pictures, only knowing the parents. line means nothing anways. Lemon seems to be the top line everyone wants, but I've seen alot of nothing special lemons and also seen alot of Holy Shoot! unknown lines. Pastel is a Pastel.
my opinion, Grade B-C, high contrast color but not alot of it and not alot of blushing. still personally high contrast color is the #1 thing I look for, id buy babies form her.
how big is she? that plays a big factor in pastels. if shes bigger than im thinking (im assuming 1000ish gram mark) then might wanna take that grade up a little bit.
