How tall is Stephanie? SuiteFights tweeted a picture of her a while back and I thought she was tall enough to fight Carmilla or Sunni. 
I can not understand how you can think that Angel who dominated in two catfights against Jackie and Emma is timid. She made them submit multiple times and was in control most of the time. Angel had also a wrestling match against Rhythm in which she broke rules and was too agressive and made it into a catfight so it had to be stopped.
I remember that Angel match with Rhythm and still love it. Rhythm thought she could push her around since Angel was shorter (even smirked at her during the staredown as she thought this short girl has nothing on me) but Angel did not let her do much at all and forced the producer to cut at the end with her aggression.
Yeah in striking, height can confer a real REACH advantage. When it comes to wrestling (and usually catfighting), "Everyone is the same height down on the floor".

Rhythm got taught a bit of a Lesson in that.
Someone asked about Angel's height. I seem to recall she is just around 5' maybe even 4'11". She is not a big girl.
One could have billed her match with Emma as the "Battle of the Hobbits" ...lol.
