Just wondering how far you feel your lips protrude into the mouthpiece, if at all? I know without a clear mouthpiece it will be difficult to prove one way or another. It seems I can get a little better tone or sizzle by letting them protrude into the mouthpiece some. Maybe a millimeter or so. It definitely feels unnatural, after all my lips don't bend like that, and I don't use pressure to get them their either they just sort of flop there with the air stream, so that isn't the purpose of my question, but to get an idea of what people do regarding that type of technique.
