taro

Hello again. I'm the guy looking for a new aikido home. I've been looking into Yoshinkan for those who haven't read my other threads. Can anyone tell me about kihon dosa? All I know is that they are forms, similar to katas which serve to condition the body's reflexes to martial situations. Let me know if my understanding is incorrect or incomplete. I think I like this principle of training, however, I'm wondering if there are any drawbacks to this method. Obviously the aikikai school sees it this way since they don't use this method of training. I understand Tomiki aikido also uses katas for similar reasons. I'm wondering how branches of aikido(aikikai) which do not make use of these forms addresses this training problem?
