Interesting stuff, I wonder if there is a clue hear as to why my RS2
setup didn't fit in my application.  I'll have to study the pix later.
While I agree completely with your logic on the flywheel issue (and
would do come to your conclusion today were I to do it again) as a data
point, my lightened 7a flywheel has been fine for 25K miles.  The only
driveability issue I believe I detect on the street is the tendency of
revs to drop faster in upshifts.  Eg I've learned not to come all the
way out of the throttle while upshifting quickly.  I did quickly wear
out the springs in the 7a clutch disc, however, before swapping to the
RS2 disc.
