tai chi shoving matches vs tomiki shoving matches

A few weeks back,  I did some hand randori with guy who had a tai chi background.  He was fun to work with and made me want to learn some tai chi moves.  So I bought a tai chi dvd and started doing some homemade tai chi in the kitchen along with the walking kata moves.  After watching  an excellent dvd by Yang Jwing Ming, I came to the non scientific conclusion that Tai Chi and Tomiki Aikido are basically the same damn thing.  Especially when you look at Hand Randori/push hands concept. Also, all the techniques are the same, both try to maintain a "bubble" in front of them.  The difference i think is how they choose to maintain the bubble. 

First of all, hand randori is called toshu randori and tai chi push hands is called tui shou.  I'm not an Oxford educated lingowist, but those two words look pretty much the same. 

Heres Yang jwing Ming the tai chi man ive been watching .   Just You tube search the guy.  He's a Tomiki gold mine of ideas.  


where have I seen this before ?: 

  

Here's a chinese Tomiki school.  some judo moves, working on # 6 from the 17, and a little slow randori looking for kuzushi.( the music is stupid, though.)  

 

A lot of times I get tripped up worrying about maintaining tanto/knife maai, and stepping off line.  You can get an off balance apparently by establishing a flow and standing your ground.  

 

 when tai chi and tomiki gets competitive it looks pretty much the same.  Shoving match randori. I dont have a problem with shoving match randori, its the same as judo randori without the chicken legging.

  

Push hands competition( looks the same)

 

and judo looks the same except they are allowed to chicken leg each other and do the old playground "fall and pull" trick

   

This mini hand sumo match looks interesting, these situations happen sometimes in Toshu randori.
