Learning Technique from YouTube

I have been watching escrima, kali and arnis stick forms until my eyes cross trying to decipher strikes, blocks and stances.  Most of the stuff on YouTube is so fast you can hardly see what is going on.   It has been very challenging although Sifu Dennis (who always see the positive side) did point out that it will help me develop my eye for detail.  Well the 'eye' is getting a real workout. So it may not reflect in my stick work yet but my brain is stuffed.
