Many advanced players prefer the open feel of Ring keys for subtle control of their tone. Intermediate and Standard model French system flutes come with key plugs to seal the hole until players have become adept at covering the holes with their fingers.

Many players find the Offset G configuration easier to play. Often teachers recommend that beginners start on these flutes, while more and more advanced players are also choosing this natural feeling configuration. Many advanced students and professionals, though, still prefer the traditional In-line formation where all the toneholes are in a straight row.

The B footjoint has an extra key enabling the player to play 1/2 step lower than the lowest note of a C foot. It also affects the sound; B footjoint enables a darker, stronger sound with good projection.
