i can guarantee you that my shomen uchi is an attack. matter of fact, we trained with striking pads regularly to make sure folks feel the strike and the level of power driving behind it.
Cool that your going all out with the Shomen attacks using pads, etc.
However... what happens when a trained striker or even grappler/wrestler comes up and you dont get a chance to execute Shomen - better yet, is there ever a chance in this scenario to use Shomen?
Only way to know is try it out with a trained grappler/wrestler and/or Thai Boxer and post it on youtube.
[Im curious and would love to see it 'live']
Again I like taking the Aikido moves to the max within that framework, but there is a lot that gets lost once the door opens up.
