I spent the afternoon with a guy who has been teaching Shotokan for over 40 years and has been doing various forms of Tai Chi for the last 15-20 years. On top of that he is about 6'3" and 250 pounds (I'm 5'6...). We played with Dan Kumite and with some moves from the Seisan Bunkai. Well, I discovered pretty quick that it ain't like working with another Uechi guy that knows what he is "supposed to do" (irony intended...). He blew all kinds of holes in what I thought I knew about how Uechi is supposed to work.
Although it was a bit "frustrating" at times, it also forced me to look at how I can adapt what I am doing to what he is doing and who he is (ex. big, very strong and very experienced). Far from diluting my Uechi, I think it probably will enrich it. Mind you, I still have a long way to go in my Uechi and lots to learn.
At the end he showed me some push hands stuff. This was not the nice gentle flowing stuff you see on TV. He sent me flyin' a couple of times. It was really facinating and practical stuff that I am sure I will be able to incorporate into my training.
Anyhow, all that to say that I think I'm now starting to understand a bit better what has been said about cross-training
