For me, Katori Shinto Ryu would be a better choice. Since getting involved with a Koryu, the knowledge, along with the living history it represents, is something that is not easily found. I have heard many stories about Obata Sensei, and while I have no doubt about his martial prowess, I do question his motives. The "worship" of him drives me nuts. From people I know who have had direct run-ins with him, his ego has gotten out of control. However, I'm not here to judge. I know it isn't for me, but I'm not here to tell other people it isn't for them.
I don't know if travel is an option for you, but there is a Tai Kai in October in Bakersfield CA, where I'm sure you could meet some good people. Here's a link to more info:
