In getting back to the original post, I have a few points that I'd like to make.
First, do not confuse the fact that a student will have stumbling blocks along their education in kenpo with the fact that those same stumbling blocks are useless material. We've all found a technique that we had trouble with. This does not make the technique less effective, merely a stumbling block that we must overcome.
Before anyone can start cutting material from their schools curriculum, they must first learn all of the curriculum and have a working proficiency of the material. Understand the in's and out of the material and the why's, not just the how's. If after labor intensive training and trial and error, about $10,000 to get your own school off the ground, establishing a student base, maintaining a student base, having your books in the black for a year, consultation with seniors in your system to run your proposed changes by, take their input and see if it is valid, and a miriade of other considerations, then by all means, change your curriculum. But, don't do it simply to reduce the volume of material for your aspiring blackbelt students to learn so that in 5 years, when they decide that 20% of what they learned to get their black is unimportant, they breakout, start their own school, and strip another 20%. Low and behold, another 5 or 6 years down the road, one of their students has the same incling, and so on, and so on, until some 5th generation student of yours in doing 5 techniques and a form to get his blackbelt.
The beauty of EPAK is that all this has been done for you. You simply have to apply sweat, determination, an open mind, and a loyal mind, and VOILA, you have yourself an effective self defense arsenal to go forth into the night and defeat all those pesky ninjas in the parking lot.
I'll liken it to a car. You can buy all the parts and assemble it yourself, apply for a DOT title, pass all the tests and requirements to make your new "creation" road worthy. Or, you can get on down to the dealership of your choice and pick you up one of those shinny new ones, already assembled, road ready, and just hop on in, pay your $3.00 a gallon, and off you go.
To quote someone, "if it aint broke, don't fix it".
Just my opinion,
