Ok so this is my theory of things.
The original FF had indentions, grooves, or whatever you want to call it, on the back of the top cover surrounding the glass.
Obviously this was to make sure the hot air got sucked equally out of the bowl to the mouthpiece path. And it worked as I can recall moist/honey deposit in those areas.
The FF2 no longer has this and it is obvious from looking at the desposits that the air being sucked away from the bowl straight to the direction of the mouthpiece side instead.
Probably one of the biggest reasons the hotspot remains towards the mouthpiece direction of the bowl, sadly I dont see a quick fix for this. Was thinking of something to make the layer between base and lid thin enough so that air is forced out of the bowl to each direction, but .... actually reducing the width of the gasket in half or so might pull this off. Think about it, if the top lid glass and the bowl are close enough together, air will be forcibly sucked from each direction.
Suppose I could buy a second top cover and play around with it. Just no idea where to get this kind of material, in thinner form.
Anyway, the mesh screen certainly did even airflow no good, and I have not yet received my ultra tiny drills so i literally smashed a few laser-cut holes on the original screen, but taking into account the 'theory' i stated above.
This sort of put the air restriction more equivalent to the original FF1 without overdoing it, and hopefully that tiny bit of extra air from the wider holes is forced to go through most of the bowl to the other side if that makes sense.
If successful I'll probably equalize it some more.
