I didn't care for the Auto-Index feature either, and neutered my press to single-stage the day I bought it. That was 30 years ago, and I haven't missed it yet. I prep my brass away from the press, but if I start with primed brass I can still load 300 rounds an hour.
You might want to look into the Adjustable Charge Bar that Lee offers, I had a dozen of the Auto-Disk powder measures, but upgraded most of them to the "Pro" configuration, it's a much better mousetrap.

As was said earlier, as long as your brass is actuating the measure properly, you're good to go.
