Re: High kicking
There is a solid reason why we do not pratice much kicking at Jiai. Taking the ukemi for it is very difficult while standing on one leg. We have praticed this in the adult class and it's very punishing on the body. I would advise not praticing kicks during open class without the approval of either Sensei or Tenley and under their supervision. If you have questions, both are very open to listening and advising. However, questions of this sort are best for after class or on Sunday's during Open Mat.
In reading the other thread about creating new techniques, you do need to be aware that all the aikido techniques you train with now are softer or alternative versions of what you'll learn in the Adult classes. Certain techniques cannot be used on teenagers due to your physiology, in that the tendons in your wrists/elbows haven't fully developed and cannot take the stress of full-speed techniques you'll learn later.
The last point you should be aware of, is in training in the kids class you're training with students who have, ballpark, the same number of months training as you. When you reach the adult classes you'll be training with students who have more years training than you've been living. In one of your threads you haven't been 'beaten up' or 'exhausted', that'll change. There are nights when I've crawled off the mat, soaked in sweat and sore as hell. Training is finding your limits and expanding them.
In reference to 'dodging bullets'. Wait a few years before you attempt that. What I would recomend is first being able to dodge an adult with a knife in a classic chest-thrust and a helluva lot less dangerous than a 9mm or .45 Once you've gotten that down, then work on bokken (think of it as a baseball bat) take aways etc... The speed and force in the adult class should humble you.
I applaud your enthusiasm, just remember there is a lot left to learn. So train often, train with intent and stick with it until you're promoted into the Adult classes where everything you know about Aikido will change and new challenges will be presented to you. Then you'll have a chance to work with kicks, and taking the falls.
