    @123toid They look great! But Nick, please add some flares to the ports. With none at all, chuffing starts at such low velocities, as I’m sure you are aware. A program called Flare-It works really well. Take the velocities from win-ISD and enter them into the program, there’s spaces for 20,25,30 and 35hz, since it is designed around a port that has a peak at 35hz, it can be translated so that the peak value is substituted into the 35hz spot and the rest of the values are in steps of 5hz, each below the last value. I have found it to be very accurate, I only came across it recently when researching port turbulences.
