best bottles for gas! please help!

Ga
I've been using the Dr Brown's bottles with Enfamil Gentlease. He still gets horrible, horrible gas. The last few nights he has been SCREAMING from gas pains. Just now, he was screaming and screaming and finally burped three big burps, and finally stopped crying. I'm switching him to a non-milk based formula because everyone but me on my side of the family and my husbands side is lactose intolerant so I am suspecting that is part of the problem, but I also think it is the bottles as well. What are the best anti-colic bottles, or what bottles do you guys use to help combat gas? I'm at my wits end. I'm also picking up probiotics for him while I'm out. Please give me any advice or recommendations!! I'm desperate at this point!
