The spoke length on the GS hub is very straightforward. http://powertap.com/...oke-length-chart.pdf
Bladed CX-Ray spokes are far easier tension, than round spokes, on a straight pull hub.
So apparently the Flo 30 has an ERD of 577.5 (http://flocycling.blogspot.com/...-30-rim-is-here.html).
The chart seems to suggest about 286 mm spokes for the Powertab GS hub, though it also says "add/subtract for nipples and washers" (http://www.powertap.com/...le%20Hub%20Chart.pdf)
As for the front, DT Swiss has an insanely detailed calculator where I have no clue how to fill in half the boxes (https://spokes-calculator.dtswiss.com/en/calculator)
Seriously, it's like cycling companies go out of their way to make this stuff impenetrable to newbies. :(
