Pyfa version 1.2.0 for Kronos is out now with all the updated stats for Freighters, Jump Freighters, Blockade Runners, etc.
I've just started playing around with it now. That extra low slot on the Prowler gives a lot of flexibility. It makes some very interesting new fits possible, like a MWD fit with under 3 second align time (with MWD off) and over 10 Au warp speed, or a fit with 44k active buffer tank and 4 sec align time (but no prop mod).
More on Prowler fits later, for now I just wanted to let everyone know the new Pyfa is available!
