Exactly. He's one of the examples I was thinking about when I started this thread. I just saw him at the San Diego bridge seminar and noted his fingers together approach then. My wing Chun brothers practice the same way and have no trouble whatsoever extending energy into uke with fingers together. In fact, many of them do it better than most Aikidoka I have touched hands with. That's one of the things I'm getting from that cross training, not just striking skill. I have frequently wondered if Doran Sensei has some wing Chun in his background, since many of his entering structures look exactly like wing Chun hand/arm positions.
Interesting - when I look at the video (granted not very good quality) I see his fingers spread as much, if not more, than when he has them together; and he allways has the thumb spread out - look at times :07, 1:54, 3:32. and 4:16 for example.
