Its assembled and I’ve started drilling with it. The first thing I noticed was how hard the floor is. I don’t have a mat. I have been thinking about if I should even get one. I like some real world or practical application of BJJ. If I got in a street fight I will use my Jiu Jitsu training but I doubt there will be a mat. The next thing I noticed is that when I tried a Kimura it doesn’t feel right. The structure of the Submission Master’s arm is a arch with no true joints. At first I didn’t like this but then I realized it felt more like a arm that is trying to do a escape. It gave me a different perspective on my Kimura technique and how to apply it. The next thing I tried was the Triangle Choke. This hurt at first because the dummy is so hard. I didn’t realize how soft real humans are. I worked my Triangle and figured out something new I hadn’t noticed before. I posted Brazilian Jiu Jitsu Submission Techniques – The Triangle and gave tips and tricks on improving your Triangle. I now can add to that getting the knee of the leg around the neck above the neck. I have also found that just moving it around, it is 70 lbs, breaks me into a sweat. It doesn’t do infinity drills so you have to reset some drills to do it over. But for the most part you can do Arm Bars, Triangles, Kimuras, and other submissions over and over on each side. For Cross Body and Mount work you sit or lay very high. You don’t have a soft gut to lay into. I also can’t hook the legs (grapevines) in mount. What it comes down to is its no full substitute for a person but it does very well for what it is intended. So far I really like it and feel it is money well spent. It is true the $560 price tag is high but it sure beats the home made version I’ve seen on YouTube.com. I think the only true competitor in its class is the Bubba. I didn’t choose the Bubba because it didn’t sit up in guard, it looks light weight, and flimsy. I’m going to start trying some escapes and sweeps on it tomorrow and see how they go.
