Looks great! So you don't have to extend and retract the stem in yours?Yeah I got it for the weekend and have been enjoying it all week... the colors are just so beautiful, in any lighting, subtle variation of dark blue grey purple, with like a salmon pink red orange, although you can hardly see them when the stem is inside the FW9 hehe:
Yes the slight taper mouthpiece is very comfortable, I also really like how far it sticks out now, very nice and does sit flush (however the narrow connector stem could be half as long, as is it goes into the ceramic pathway about halfway, so not a big deal and still gives the full pathway effect, and it actually means it could be pulled out a tiny bit further for a little extra if I wanted although then it would wobble more of course) helping it feel much more secure, with only the slight wobble back and forth possible now (which is due to the extra room in the FW9 wood there, probably could be countered with extra felt if desired)
Now that I have had some time with it, I can say it is not necessarily that different, although it definitely is a little different... Mine of course is slightly longer, which helps with slightly more cooling, not only that it is the wider diameter part that is longer as I made the narrower tube shorter... I think the little taper mouthpiece is great yeah and he can make different style mouthpieces depending on what you want (in his drops he has been doing pinch flat versions as well)... the airflow is wide open, the cooling bricks move around a little bit, so there is enough room that I don't think cleaning will be any issue with iso and hot water, they do seem to offer some nice cooling effect as slight obstruction in the pathway, there is also a spike on either end to keep them in, though the stock stem has more spikes and a rotated configuration for them, they don't cool that strongly either anyway... Something that really is nice with the design of the FW9 is that ceramic elbow pathway, gives you some right angle cooling before it enters the glass stem, however I also like to ride the low temps partly for the smoother hits personally... So yeah quite a few variables here, though I hope it helps you
My all red brick and the custom shows to be delivered tomorrow and I can't wait. I'll probably put my current yellow/gray/blue stem up for sale.
