"Professionals are predictable. It's the amateurs you have to watch out for."
I find this above statement to be true. I work in a field where physical conflict is a weekly occurance. I've been doing so for the past 8 years. I know (for me) what works and what doesn't when a uke isn't trained or wants to follow.
I use a lot of chokes (kubishime) in my technique. Why? Because it negates any size advantage. Also, aikido, used in a real world setting, has to be broken down into basics. You must also be able to read the body of the uke.
Like I teach my students:
1)Keep your system simple.
2)You must have 100 % intent when doing a technique
3) Be prepared to improvise and change your technique at a moments noctice
Thanks for the replies!
