The cage has its ups and downs. Practicing like you play is important, but I feel like you get more injuries training in a cage. Most all promotions at this point have one, so if someone at your school is fighting mma, it's good to get some time in one. Fingers and toes and ears get caught and it can not be much fun at times. You can get some padded walls to practice wall walking and wall related drills. That's a tough call the more I think about it. Good question.
