By now everybody has seen Marcelo's high-elbow guillotine, and it's generally regarded as a superior alternative to the traditional way of doing it (with your elbow close to your own body). So does that mean we should stop teaching the low-elbow way? Is there any benefit to doing it the traditional way anymore? Anybody tried out the high-elbow and then went back to the low-elbow? I'm asking because personally, I've never been able to get the high elbow working well. I'm trying to figure out if it's just because I haven't put enough reps in, or if it's just not always the right move for everybody?
