It looks like you can finally buy the new FSA SMR II stem. It is a -10, but if you run it for internal routing, there is quite a bit of drop at the bar clamp because of the design. I suspect this stem will result in a position lower than the -17 degree option from SQ lab.
Unfortunately, stems aren't dimensioned to reflect eventual bar height as stack clamping height and drop at the bar clamp can be hard to find. I expect to pick one of these up in the next few weeks, as soon as I can get one from a source other than BikeInn in the 130mm length.
It's a decent price and available in the 120mm size here:
