Re: changing aikido styles (rant)
To me it sounds like it could be a really good opportunity, given that you see certain strengths that they have that you don't. It might be a chance for you to work on those aspects of your aikido. If you train their way, at least for a while, and concentrate your attention on the things that they're better at then you, you might find you can really improve those aspects of your own aikido. And you can keep mentally aware of your and your partner's potential openings even if it isn't appropriate to actually hit them.
On the other hand, if there's another dojo you can get to that seems to you to have those strengths without also having some of the weaknesses you feel you see, that might be even better in the long run. Because in the long term it's hard to fully commit yourself to a dojo and teacher if you feel they're weak in an area that you feel is important.
