I wasn't so sure about adding Bashir to the crew but it makes sense that he has been chosen for this mission. I'm curious to see what you'll do with him.
I like that Quingley ordered the slipstream jump even if he disobeyed orders from Icheb. Nothing like having a slightly flawed character around whose humanity might outweigh his sense of duty. It remains to be seen if he made horrible mistake.
In any case, the story will be richer for it. Well done.
