What sisters dont have Jetbikes.....
Not exactly true, check the Black codex edition.
Just like they can have landspeeders....
This is the components that would go together to make up the sisters Jetbikke, for squadrons.
This way they would look sympatico with the landspeeders...
This is the landspeeder that was the base at the time of the release of the sisters. Jetbikes would be the logical extension on the same model design.
That would give the sisters some hover heavy support with speed. :P
I am putting this here as I dont have time to model it up for DOW.
