Re: mouthpiece for note bending?
The fingering I use for F# when i dont' use my high f# key is: bkey, gkey, lower fkey, ebkey, and try it also with the dkey added. Different horns are able to use different fingerings, and you just need to experiment with this one and others that u find to figure out which one comes out the easiest. Try playing up into the note instead of going for it at the start. This will get your throut in the right position and will make it easier. Good luck
