Re: THE HEEL TOE THREAD
I play the slide technique, and what I've just learned is that in order for it to work, the foot must slide. The sole of the human foot has a good grip, try wearing some socks or footwear that has less friction.
Hopefully this theory can be applied to the heel toe technique.
And don't expect to grasp it overnight. Some drummers take weeks, others may take years. Just do a few minutes practicing this each day, and start slow. Eventually your muscle will memorize your movements and it will all feel natural.
Just my 2 cents.
