Hi everyone, first time poster here. My A-5 is in the mail on its way to me, and I'm thinking about getting an e-grip for it. I heard from a friend that there is an old style one and a new style W.A.S. one. What's the difference? He says that on one of them you have to pull the trigger three times or some junk like that before it will fire full auto; is this true? I want to buy the one that I can set to full auto and just press the trigger once and have it fire full auto. Which one is that... the old one or the new one with the W.A.S. board? Also, which one is better (in your opinion) and why? Thanks.
