Flushing a Rocky Balboa x Who Cow

I am taking this donor to get her flushed this weekend, pictured as a heifer.  This cow is very stout, and extremely hairy.  I was going to flush her to Fu Man Chu and Monopoly already.  My question to everyone is this: Has anyone had any Mercedes Benz calves, and if so, do you think he will work on her?  She is a 1/4 Maine, looking to put some Maine back in her for females.  Or would I-80 be a better option?  The I-80 she was carrying when I bought her was a bull calf that I kept intact.  He slipped and fell on ice as a coming yearling and ruptured a major artery, bled out internally overnight.

Comfort Zone, Unstoppable Th,and what has to be the best young bull in years-Safe and Sound-TH O0

I second the Comfort Zone and Unstoppable, but have no experience with Safe and Sound. I really like my Comfort Zone calves and he is a Mercedes Benz son.

Thank you guys

I would try safe and sound, his dam is a belly dragger of a cow.  Id probably stay away from unstoppable, i think her neck is too short for him.  I feel he needs to be used on a giraffe necked one to work good.  Id try here i am on her for steers.

SAFE and Sound has sired A TON of good ones that Ive seen on sales, blogs etc-hes a game changer but HES STOUT not goosey- ALM EXCEL 80 is a triple clean "version" of SAFE And Sound-and is bred ALOT like him-hes a full sib to Allison Manchesters Champion bred and owned Maintainer female at the maine JR Nationals-and has the same Shorthorn back there (ALM CHILLER) from Allisons Family ( a VERY good CE bull.) along with 1-80 and Northern Improvement-ABOUT AS GOOD A PEDIGREE AS YOU COULD WRITE FOR STOUT MATERNAL CATTLE-and HE IS FLAT OUT THICK-and DEEP RIBBED O0
