OK so the answer appears to be the OEM fly and clutch makes the noise go away. That is testimony from 4 members on NAISOC who had the noise, and upon reverting back to stock, noise went away, I will be doing this soon, as I do not see the benefit of the LWFW over stock in the first place, at least not worth the hassle this has caused.
My setup was a 2007 WRX flywheel and matching exedy clutch kit.
All kinds of people trying to diagnose, I think replacing the clutch is cheaper than a tranny rebuild and sounds a whole lot cheaper too, worth a try.
