I´m not at all sure that hidari/migi no awase is all that you need. While I see them as very important in getting a feel for awase the fact that you are locked down to a strict form based training makes it very easy to not learn reading intent at all . I think that slow focused training where uke just is doing different serious attacks (bukiwaza or taijutsu) and tori focuses on seeing the attack as it is and just avoiding it is the way to go, then of course incrementally increase speed and power as you get better.
Thanks, I was looking for an isolated drill specific to working on intent. Certainly all the buki waza (or any old waza) present an opportunity to use intent but along with a whole bunch of other stuff. Being able to seperate the variables helps with working on each component. I'm aware that some variables may not be amenable to that approach but I'm ever hopeful.
