best proven calving ease sire available in Canada?

Just wondering what the best calving ease sire is that is available in Canada?  Forget about Ali, can't get him here anymore and semen from clones is not allowed in Canada.

Here are some that I am aware of that we can get here at this time, Rocky Balboa, Tyson, Giogolo Joe, and Hard Core.

Any thoughts out there?  Feel free to add some to the list, whether you know if they are available her or not.

Thanks in advance.

I just bought some rocky balboa semen. I have heard he keeps them small but they are not a waste of a calf either.

did you buy ROCKY semen throgh SEMEX or from LAUTNER?I live in ONTARIO and would like to use him.

I just sent you a PM about Rocky.

You won't bust her if you breed her Buster.

We actually got it through ABS. We are good friends with the guy and was able to get it.
