Everyone don't forget to split up your 'blocks'. We will need to be able to burn through about 720 blocks per day and those 720 won't be eligible to stake again until another 7 days. I just split into a bunch of 4 FLY blocks. I think it will be good if we get a lot of people to go pretty small like this (3-10). 25 FLY blocks as stated before should work well too, but we also need to create a high quantity of blocks that will be ready to phase us off of PoW.
You could always just make a script that sends 1 transaction every 2 minutes over 7 days.
