Buffet Crampon Prodige Bb-Clarinet 17/6

Me and my clarinet teacher discovered that the lever on the upper joint that you press to play A note is positioned too far from the body, making it very uncomfortable to quickly reposition your left index finger from F# note to A note. We compared this lever with other clarinets (both cheaper and more expensive than this one) and none of them had this issue. On these other clarinets my index finger can just slide from F# hole to an A lever without any issue, while on Prodige I have to raise it a bit (and that will result in clarinet playing short G note) and then press the A lever.

This lever position makeы playing the clarinet pretty much uncomfortable. Certainly I struggle with fast playing when the melody has an A note of 1st octave (concert G since this is a Bb transposing instrument)...
