I have trained at Cobrinha's several times, all during the advanced class which Cobrinha himself teaches.
It has a nice facility, although the bathroom seemed small for the sheer amount of students that train. It feels very corporate. I don't mean that necessarily in a negative light, but it felt factory-like. It is stone cold silent during drilling, they have sign-ins with attendance cards because a class could easily have 50-60 students, and there is a timer to switch turns drilling. Depending on how you like to approach your training, these things could be a good thing or a bad thing.
The general size of the students are smaller on average. I was the largest guy there by a long shot both times, and the techniques shown were very much a "small man's game". Very flexible/mobile oriented. Fantastic stuff BTW.
I would just go there and check it out. You should check out many gyms and see which one is good for your personality. That drive from Burbank is unrealistic.
Competition schools tend to be "clique-y" in my experience. As far as price, I think it is a very fair price considering how many classes they offer. They have classes in the morning, afternoon, and night, any kind of schedule would be able to train there easily.
