Re: Two teachers...
One example I know of was my own Sensei. When he was in California, he trained in 3 dojos at one time. He made sure to DO what was being taught at the dojo at the time he was there, and not try to mix things up. He also never corrected or pointed out,"This is how they do it elsewhere." as was mentioned before.
Listen to Ledyard Sensei. I'm sure he didn't mean you nessecarily. He is a TREMENDOUS resource on Aiki-web and has a wealth of knowledge we should all hope to aspire to.
Good luck! Let us know how it works out for you!
