Hi Brian,
I agree, slightly over 4 ounces for the whole stab w/ elevators is a really good weight.
One of the main reasons i don't use 0.3 or heavier grades of carbon veil outside. Weight sounds great but the actual application takes more dope than one thinks.
Years ago when I first used carbon veil, the 0.5 variety was the first weight I used. It was not satisfactory weight-wise. Wound up snading it all off, what a PITA. But boy was it stiff. Anyway, the 0.2 was the one that produced the better results on the outside. Eventually I returned to light paper on the outside and veil on the inside. It seems to be the best of all the worlds so to speak, for those that love to finish in paint rather than wrinkle kote.
