Everyone has their own aikido.
I was lucky to find a sensei who believed in hard practice. Even in his eighties his aikido was incredibly strong. You need to find the sensei whose style you most admire.
There is a quote that when O'Sensei was asked why his aikido was so strong and yet flowing, he replied it was 50 years of kihon!
Everyone wants the flowing aikido and the power, you just have to put in your fifty years.....and how many want to do that.
The answer lies in the beginning as Percy Thrower used to say......
I practice kihon almost everyday.....
