I have to agree with Cotnijoe here. In your own words "if you so much as move slightly, you have to readjust these" - that sounds far from optimal.
I'm saying this from personal experience, my first customs (8.A) were very loose. But since I had no reference, I just assumed that that was the deal. But in the end, it takes away from the daily pleasure. I was always wondering if I was getting the right sound at the moment as it changed with the seal. Another big personal issue (that will not apply for most) is that it's not possible to use heavier upgrade cables as they constantly tug them out of your ears with such a fit.
Of course it sucks to wait, but EE's outstanding turnover time of 2 weeks is almost negligible, and for you it's within the US. Heir took 6 weeks, plus 2 weeks transit time of the the ear impressions from Europe and another week shipping back.
Otherwise great impressions! (With one sidenote that it seems you mention the wooden faceplates affect the sound, which I'm not so sure I believe as there is no resonance from the drivers with the material of the faceplate. I don't see which physics would support that.)
