Recently (well, a year ago) worked with a Key Grip who is a good friend of mine who tried to sell me on a different system for levelling track. We've all used wedges. They're our friends, we understand them, they're ultimately expendable. There is another system that uses wooden pads, roughly 4'' square, of varying thicknesses, all color coded. They pack very neatly in a crate by color. They go from about 1/8" up to , I guess 2" in thickness. While laying the track, you would, depending on what thickness you need, yell, "Give me a green!" or "give me a red!"
You get the idea.
I tried. I really did. My Key Grip friend swears by it. I'm sure he's right (he usually is about these things) but I just couldn't get used to it. Finally, after about two days of, "Give me a green, no, a re... where's a yellow?" I revolted and offered my resignation if he didn't get me a barrel of good old fashioned wedges (Well, that's not exactly how I worded it, but I'm much calmer now).
When the wedges arrived, I cut my track laying time by approximately half.
I've no doubt that this system works great for those used to it. Obviously a track leveled on flat pads, rather than sloped wedges will tend to stay in one place longer, I just didn't have the patience. Maybe I'm too set in my ways. I barely have enough capacity left in my brain as it is without having to remember how thick a "red" is. I know Jim Kwiatkowski's guys use it (Munich, Minority Report, every Spielberg movie since Schindler's List). So I know it works.
Anyway, anyone use this system?
