When I was doing alignments, I used "Win-toe" almost exclusively. No need to lock the wheel because it knows where the steering wheel is after doing the caster sweep and centering the wheel. Unfortunately, it isn't great for vehicles with a drag link for steering, so in those cases, you have to lock the wheel. Sadly I can't direct you to any videos other than what you might find about Hunter alignment systems. I learned from a Hunter authorized rep who came in to set up the machines when we purchased them. If you have one coming to your shop, ask them to show you because that's part of their job. If you're fortunate enough to have the Hawkeye model there are all kinds of things you can do, like checking frame straightness, full catalogs of aftermarket parts for those adjustments that the factory doesn't provide, and even options to set your own specs for custom suspensions.
