I'm getting my best friend a SB Pro for his birthday, but I had also considered an ENO Doublenest so he could put his girlfriend in there as well. I'm just wondering if the SB Pro is large enough for two people, assuming the weight isn't too much. He's a pretty hefty guy, she's super skinny. I'd hate for them to try piling on and wreck the hammock. (I'm getting the SB Pro because he wanted a bug net).
