I strongly disagree with this. Aikido is much bigger than one club and one instructor, and there is nothing disingenuous about wanting more than one instructor and one club can give you, especially in the case of someone like Philip who already has a lot of martial arts experience..
Every instructor with serious reputation has a distinguish system of teaching. If you take some elements out of this system they will have little value or no meaning at all. So if you jump from one system to another you will learn nothing significant even with some training background in other MA.
That is why it is so important to choose right instructor and not a ‘style'.
