I play with a group, who is all relatively new. One of the things we do is spot for each other. Whoever is throwing most consistent throws first then moves about halfway down to watch from behind a tree or something. We like to play pinball off trees accidentally. This helps us spot where they truly fall on doglegs and such.
Another lesson I've had to learn hard is take a safety shot that leaves you open in tight areas, even if you get less D. Don't try to muscle them through a tight area with a bad setup for your next shot.
Always mark where the disc lands by a marker. Mainly a tree, rock, or similar to locate once you walk out from the tee. I've had several where I threw and they were 40-50' further than I thought they'd be, from a tree ricochet.
Last, color is important, but it depends on where you play. Here, it's mostly wooded. I tend to stay away from anything green, dark red, or dark blue. I also stay away from champion glow and black anything. My preferences are orange, bright pink or red, yellow, or chartreuse.
I don't know what people will think of this, but I saw a guy the other day who had something like this put on both sides of his discs. It seems like this would change the flight a little, but I don't really know. He pulled a flashlight out to see the reflection? Anyone else ever tried this?http://www.reflectiveshapes.com/Reflect ... ircles.htm
