Half the battle is sorted before you reach the course. Build your bag in the app, see what each disc actually does, and pack the discs that suit the layout you're about to play. It also helps you spot the gaps in your bag you didn't know you had.
Add each disc you throw. Name it, set the type, and log its flight numbers. Once it's all in there you've got the full picture of what you're carrying, instead of a vague idea and a few discs you forgot you owned.
Most of us carry three discs that do nearly the same thing and nothing that handles a long, right-finishing line. With your bag laid out, those gaps are easy to see. Not just speed and stability, but the actual flight paths you can and can't cover. Then you know what's worth adding next.
Your bag feeds straight into the Caddie. Planning a course full of tight, wooded lines? You'll see whether you've actually got the discs for it before you turn up, not after a bogey on hole 3. Draw a line, pick the disc for it from your bag, flight numbers and all.
