I have an mma tournament coming up and one of my opponents does combat aikido. Does anyone have any experience against this style. I have little knowledge of it and I don't know if they have any ground training or standup only. Fight is May 31 here in Manila amatuer with the headgear. I also have to fight two Muay Thai guys but I know enough about Muay Thai to have a gameplan at least. Thanks in advance for any help.
