Agree with you 100% there. Old Chinese saying said, "Everything has counter. Only maximum hardness (power) and maximum speed has no counter". If you can swing a 100 lb long sword, nobody can stand 6 feet in front of you. Two of my favor tricks are I - throw a back fist, when my opponent blocks it, I'll borrow his force, spin my arm, and change my back fist into a hook (or hay-maker). - pull my opponent, when he resists, I'll borrow his force, change my pulling into pushing. IMO, you have to give before you can take. If you offer no force, you will have no force to borrow. If you worry about your opponent may borrow your initial force, the borrow force game may not be your game.
