I agree 100%
Aikido is not for everyone, I don't think any art is.
Years back I took a Judo class and a karate class and didn't hesitate to choose karate. I felt that judo was too soft at the time and what I needed was a self defence. Looking back I should have taken judo for the long-term effects.
If you are 6'6'' and very strong almost any MA could be good for you.
