Not sure if you're talking to the other(F5) guy or me;
If me, I DO use a handheld meter. Hardly ever use the in-camera meter unless I seemingly forgot to put the meter in the bag prior to departure .
A cinema-meter in fact, a Spectra IV digital. Wonderful meter, super accurate, and great for VERY low-light exposures as well(which I'm starting to do more of, @ dusk, etc...)
