Never said there is no waza - did say that waza will not develop aiki, but waza can (and should) be used to help understand the effectiveness of aiki. Aiki development is separate from learning waza forms - however, they can be brought together as long you understand the relationship between them; which waza leading to aiki is not one of them, IMO.
Youre right, there is allways waza and whether or not it develops understanding of or the ability to develop aiki is the same to me.
The buttomline is that waza is indistutable in terms of learning aikido and so is aiki in terms of enhancing your training over time. Afterall were all doing aikiDO- no ?
