How complicated ya wanna make this? LOL
1. Decide what length you want based upon your actual bow and rest set-up (actually measure)
2. Decide what weight head you want to use, and style fletching
3. Decide what you want your finished arrow weight to be based upon how fast you want your bow to shoot
4. Choose the appropriate shaft that will be spined correctly for your bow and give you the finished arrow weight you want at that length and with those components
I agree finding the proper length for your arrows should be simple. Then you can build the arrow from there.
