I like to add some thoughts and I don´t want to sell it to you as everlasting truth but do look at it like an input to think about.
My experiences goes that way that it´s all about honesty!!!
You can lie to your self and you can lie to weaker or anxiously students but you can´t lie to an aggressive fighter that´s even bigger or stronger than you.
I tell you what ever you see in Videos or on photos has nothing to do with reality.
If you as I stupid wisely did watch instructional videos and try to learn it by practicing it with your students there is a big problem.
You have to be aware of the fact that the demonstrating sifu and his favorite student has arranged everything.
If the sifu demonstrates lop sao and crossing hand techniques the student let pull down his hands very easyly and after his hands are drawn he willing holds down his crossed hands so that his sifu can demonstrate any fancifully techniques he likes.
If the student would try to defend him self as hard as he could you would see that 90 percent of what you see in the video won´t work any longer.
It also has to do with big names.
If you would go to GJK,PhB or GL to train with them or to learn from them you would never try to attack them as hard as you could because you are afraid of your armageddon.
So you won´t be a threat for them anyway and you won´t stress their positions very hard so that they mustn´t take a very good position or body structure to deflect your attacks.It´s a bit like driving a taxi.If the driver tells you that he want to have 10 Euro,Dollar or what ever you certainly wouldn´t say no I give you a hundred.You will only give as much as you absolute have to.
Some of them can give much more and some of them only pretend that they can give much more...
What happens if they realy have to deal an enemy who isn´t afraid of their name or their sifu´s name you can try to imagine on your own.Open your eyes and test it on your own what works best in training.
Tell your best student or sparrings partner to attack you as hard as he could and then try it out wich turning works best.
Be honest to your self and if it have to be butcher your holy cows.
my kindly regards
