Hi Jørgen, I just got home from class then. I asked if there were any more training opportunities during the weeks, and it looks like I'll be able to do some mid-week training (some weeks) with one of the Black Belts from the school. I also have a (much more experienced than I) friend who does a different style of Aikido, who said that he'd like to train with me sometimes as well. So, given those points, I think I'll stick with just Aikido for at least a few months, possibly/probably longer. If I really feel like it, I can always get a punching bag and practice a bit of the old MMA stuff I used to do.
Thanks for replying
