I am also considering using 2d6 for S&S attributes. I haven't sat with it yet as I just finished my first S&S session. I talked about it with the players and they had no problem with it. Ultimately, unless you're doing something with the actual attribute numbers, it's really only the mod that matters. Yet, if I just go to a mod instead of all the numbers, I figure I might as well play FUDGE. I'm using a HackMaster style % on every attribute that can be raised upon leveling.
