I didnt make that clear,
I ment every style ,look into all of them so you can see what their strengths and weakness are watch the top men in each.Get on the mat as well and just soak it all in.Dont tell them what or where you are comming from or it will defeat the purpose and you will have to deal with their egos aimed at your style.
We went there to each as total beginers just for the exersize and we soaked up everything we could.
It was an exersize for us to do years ago in one school and we had to write a theisis on the pros and cons of each style under different circumstances before we could steak our own flag in ground.
