I only have done somewhat karate. I would like to do Judo or BJJ to add to as a ground and takedown base as Isshinryu is mainly striking. I'm not sure which to do so I would like everyone's opinion on that.
Also, if I am to join a school what should I look for in an instructor because it seems to me BJJ is very competitive and all of these people have said they've trained this person and that person, so what?
Finally, how much do the average classes cost per year, and does it really usually take people 10 years to earn a BJJ black belt?
