This sounds like one of the most important choices this community has to make. Lets hope it goes well.
Would personally prefer 7/11 or 8/11 is needed to complete a transaction for extra security. Could even do 6/11 is okay but it takes two days for transaction to post unless 8/11 agree and none of the others oppose.
I agree with you that I think 7/11 is better than 6/11. We could certainly do another vote in the future to change it if it doesn't get altered this particular round. I would definitely vote for 7/11 over 6/11. I would have to think about 8/11 and the implications, but I think it could work as well.
