Did the Maybo PI a couple of years back. Complete and utter waste of time and money. Yes we got the course books at the end but learned nothing of any value. We were fortunate as most of the bods on our course were experienced DS and/or practitioners of Martial Arts of one sort or another anyway. We were able to provide solutions to the many problems that the Maybo didn't work for, which was pretty much all of them.
Our instructor was there just to deliver the course, not pick faults in it, which he did. It's a wholly unnecessary, waste of time and money. Two quick examples were the instructor getting launched across the room whilst demonstrating a technique, when the lad he was demonstrating it on decided not to leave and basically shrugged his shoulders, taking the instructor totally off balance and to the floor.
The second was whilst me and the instructor were supposed to be "wrapping" one of the bigger lads on the course (6ft 5, 30ish stone). Instructor assured us that this would work, couldn't fail etc, Maybo wouldn't advise it if it was s*it. Ended up with the two of us getting crushed against the wall, my hand almost broken in the process and me going for the only option I had left which was a rear naked choke and standing on the back of Brendans knee to bring him down. Complete s*it.
Regardless of whether or not the students receive the course book, the whole Maybo PI course is a waste of time and effort. Totally useless and impractical in every situation I've ever faced. Ranks alongside "Stop! Stop! Stop!" as a method of SIA practice which wasn't thought through.
Do it if necessary, ignore everything you've been shown and get some proper lessons.
We are the willing, led by the unknowing, doing the impossible, for the ungrateful, we have now done so much, for so long - for so many, with so little, we can now do anything with nothing!!!
