I think it has two few techniques and the execution of the techniques at that aren't very good. You would think you could perform the only techniques you know well. I think boxing would be better for simplicity. OR muy thai. There is no way you could do any of those attacks against a serious muy thai practitioner and the execution of their elbows and kicks are very good. Plus, they have great conditioning and can take a good hit.
