Windtalker , your English / American comprehension skills are rather lacking , when did I say the Straight Blast was not effective against an opponent moving back? I didn't! It is but that is not as CallSign put it the only time you can use it. You've not seen BJJ in Wing Chun, eh but you've never trained with any Wing Chun guys, and are rather clueless about it, feel free to correct me if I'm wrong. Randy Williams has added BBJ, and modified it to add to his Wing Chun, as have others. As for Systema, have met and trained with a Systema guy high ranking, have seen many of the DVD's,etc too. You avoided saying anything regarding the clips of Systema I posted, with the amazing soft strikes, etc (or the fact Bullshido has open challenge to prove they work, no Systema person has yet come forth to prove it). Regarding Israeli martial arts or JKD , I know far more on either and have trained with more people in both also than yourself. Big deal? It's just that you keep going on about 'experience' when you haven't got all that much yourself. As you now do Krav Maga (KMW) have you trained in any Israeli martial arts other than the Civilan KM Dareen Levine, etc do? There is far more to it than that, and the Civilan stuff is rather limited , besides the fact -in Civilan stuff they teach people to hurt attackers, in others they teach you to kill e.g. Military / Special Forces would never use the Civilian stuff, if they are caught unarmed they've messed up probably and need to kill inflict serious injury fast. You are entitled to your opinions and I respect them, but maybe take a closer look at what you know or have done before you go on about 'experience' , etc.
