An instrument with a small bore will tend to have lower resistance than that with a larger bore; less air would be required to fill the instrument, making it easier to play for a beginner. Larger bore instruments tend to have more projection and a larger sound presence.
The quality of the pad will have a great effect on the instrument; low quality pads may tear or constantly move out of adjustments, which causes leaks. Can affect a single note, or the entire instrument.
