I agree for the most part. Something else to consider...

During prototyping, the question may arise of whether or not to apply the flywheel effect to prevent momentum loss as the ball moves through the wheel (move the mass towards the outside of the wheel). If the flywheel effect is used, the question becomes "does the wheel slow down in a short enough amount of time so as to not shoot the balls too far or too hard as the robot drives towards the basket?".

If the flywheel effect isn't applied (e.g. use of light skyway wheels), then there are other tradeoffs too (spin the wheel faster than needed because of anticipated slow-down, control feed rate, less ball contact time, etc). This also makes it mostly easier to control distance with shooter wheel speed since the wheel is more responsive to [lack of] motor input.

We are still (sorta) wrestling with this tradeoff. For now, we're making the flywheel weight adjustable and forgoing the adjustable angle. Test test test .
