Simmy bull x comm angus

I think I have narrowed my search down to 2 simmental bulls to use on some commercial angus cows.  I am looking at either Rendition or Make it Rain.  Any thoughts between these 2 bulls?  If anyone has any calf pictures out of these bulls, a PM would be great.  I know there have been a lot of different suggestions on this board for simmental bulls on angus cows like Fat Butt or Macho, but I am looking for something a little different.  Any help or input would be appreciated.  Thanks.

Here is our Rendition calf. He is a late November, and has not been cut (yet). He is deep and soggy, I would just like to see a little more mass in his rear. His dam is a Westfall Crossfire 6 year old, and has tons of power. He has only been on grass and milk, and we just brought him in to clip off his winter coat a few weeks ago to see what was under all that hair!!!

We have a Make It Rain due in the fall, out of the big rumped cow in the picture to the right of the calf.

What's your goal with the resulting calves? I primarily use Sim bulls on commercial Angus cows.

Show heifer prospect and eventually replacement female.
