Re: Closed fist whilst blocking
Can't answer all your questions. But I can say that, the way Kenpo blocks are structured, the blocking arm is much more anatomically solid if the fist is closed AS the block lands. It should be open in chamber (in practice) and through the allignment sequence, then close as the block is aplied.
The Kaju school here does their blocks with an open hand. However, their blocks are more sweeping and the angle at the elbow is more open, arm more extended. Structurally, with the extended arm, the open hand works better. They lean out to create distance when they block- not an in close system. It is more effective than it sounds, but in my opinion not nearly as effective or versatile as Kenpo blocks. I did consider training with them, though, because the blocks are much easier on my body.
