Hello findog!
An important part of Jeet Kune Do attack strategy is Lin Sil Die Dar, which means simultaneous defense and attack. It is advantageous to parry and strike simultaneously, as you do not miss a beat where there is an opportunity to attack. Now, just parrying to be parrying is another story. That is pretty much wasted motion as far as I'm concerned! Also, technically, "blocking" should not exist in Jeet Kune Do, as it is force against force to stop an incoming attack. Only block as a last resort to keep from getting creamed when you weren't properly prepared to defend!
Keep Blasting!
