I would think 8's would get you in as even if it gaps in the am it may drop back a little to fill the gaps
Although, if you wouldn't mind paying 9's, go ahead with the 9's because this thing with the buzz it's got going around may just blow right out of trips! I have an average of 9's in this thing & have been here quite a while. I just wish I was one of these lucky guys who bought in at .0001-.0004!
IMO, if you don't mind paying the .0009 for some or all of your order, then put it at .0009 - if the price doesn't immediately jump up, then your order will fill at whatever the current market price is (assuming that the current market price has not exceeded your bid price). I play 'em like that a lot if I really want the stock.
