I've got a Starlite, and have tried using the Zone system functionality, but find it too finicky. It's annoying having to first switch to Zone mode, take the readings, and then switch back to F or T mode to get the required f-stop and time combination.
Nowadays, I keep it on EV mode, and use the pseudo-analog scale at the bottom to determine the f-stop. You measure the lightest and darkest items - in the same way as the zone system - set the time to an appropriate value, and then set the f-stop to +2 (or whatever suits you) above the reading for the darkest value. For example, if the time is 1/30 sec and the readings on the scale range from 2.8 to 32, I would set the f-stop to 5.6. (I am talking about B/W, of course!)
(Digital meters are great in some ways - with spot metering, multiple readings, etc - but I really miss the good-old, user-friendly dial on the Weston Euro Master.)
