Bull semen in tank and what types of cows to use it on.

I really appreciate this site.  I enjoy reading it every day.  Like said in earlier posts I am kind of new to the AI'ing and raising these types of calves.  This is a family ordeal and all of us really enjoy it.

I was looking in our semen tank and noticed some older bulls and was wondering what type of cow this semen would be used for.  I have looked on the internet and not a whole lot mentioned.  Is this semen just out dated or could it be of use?  thanks for everyones input.

The bulls that I am asking about are:: MJT Easy,  Evander, and Foreplay.  With MJT EASY being the one I cant find to much info on.

Thanks again for any input.

seems like a lightly used potentially low birth weight bull.

some what obscure pedigree on top.

if i were to guess, i'd use him on some cows with volume and ability to throw lower quarter and perhaps need some style and some frame.
