Rubin Royal, Rubin Cortes and Rubin Action

[Tango]

Hello,

I am thinking off breeding one off my mares by Rubin Royal, Rubin Action or Rubin Cortes. What do you think off those stallions and do you know how they breed ?
I need a stallion who breeds big, uphill and with a good rolling canter. Because I want to try to improve those 3 qualities by my mare .
Hope you all can give me loads of information about those stallions because I only saw them on a picture and Rubin Royal on a short video on internet.
Do Rubin Cortes and Rubn Action move well ?

Thank you !

Oh, forgot to write that you can give an answer in German. I can read german but not write it. Sorry.
