I hope you guys and girls here can help me out in making my decision, or perhaps suggest other things I didn't even know about!
Thank you in advance!
So if I understood well you want to study aikido max 2 years and get a black belt in 'combat' oriented style? Then you will move to bjj or MMA to continue study?
My advice is to not waste your time for aikido training. Even if you get black belt in 1 year, it means nothing at all outside of this particular dojo. Especially for MMA folks, they will simply destroy you in 10 seconds. Better start MMA immediately. I don't see any benefit you can get from your short aikido training.
