bale densities

I currently have a 570 NH and am looking at picking up a sb44 small baler.
I know I am going from 14x18 to 16x18 but was wondering if going from conventional to inline can affect the bale density.
I am used to running heavy grass here and can do 70-75 lbs in a normal first cut so what can I expect as a bale weight?

Also, how do in lines do in straw?
