Having tried many mouthpieces, from many manufacturers, I came across the Sparx mouthpiece (from the review on 4barsrest).
From the first time I played using my Sparx 3DV I noticed excellent intonation, greater comfort, incredibly even response, more security at the extremes of my range, and lovely sweet, rich tone with lots of presence.
The Sparx mouthpiece makes me want to play all the time.
(great customer service, as well).
