my instructor is a 3rd dan aikikai who got his 3rd dan after more than 10 years which I guess is quite some time in aikikai and he was some kind of a "street" person so he tends to get into some fights. but 95% at the time he was teaching class, he always teaches henka waza. I have no problem in learning something new, but the problem is when I think some of his henka waza isn't effective. I know this because I have been the one he used as uke most of the time. when he's doing the technique, there's an opening for a punch or a kick or elbow strike which doesn't occur as much in kihon waza (that's why I like kihon waza and repect O Sensei so much for his research on human body). in some other times, I deliberately loosen my grip so that he doesn't look bad when performing a technique.
I know I should respect him for teaching. maybe this is just a rant or sharing.. but I would like to know if anyone has had similar experience..
I mean no disrespect to your instructor when I say that sandan does not mean your instructor has mastered Henka Waza.There may well be flaws in his waza.If indeed you see openings in your Senseis waza, surely it would have been better to quietly ask him /exchange views with him rather than post this type of blog .
Frankly I think you show little respect for your instructor and lack courage when you fail to discuss this issue with your instructor.
As a senior?in your dojo, in my opinion you should have more respect to your Sensei.I believe you have undermined your Sensei.
