Hi, I need some help matching one of my mares to a straw that I bought not realizing that I already had a different more expensive one to go into the same embryo and now I have to use it this RO

First I need to figure out wich straw to use for embryo

or

the mare is

whatever is better for the embryo goes and the other straw will go to either one of these, what one is a better fit

Thank you for your opinion, which mare do you think helium should be for? I have some EWE mares to that are tracked if they really don't match

I still need help with the straw for helium please
