Nikolas: They are fine for some, bad for others. And I write this without ever playing the mouthpiece you queried.
Welcome to the WWF. Mouthpieces are very personal - what plays well for me is not everyone's choice. In fact, I'm betting many players wouldn't like my set-ups on clarinet and saxophones. The only times I had agreements with other players is when they liked the same mouthpiece I was using - and for the same reasons. THEN, we were able to compare our experiences with other mouthpieces and arrive at a GENERAL opinion.
Many of the pieces that have been "recommended" over the years on this forum and other forums, have proven almost worthless when I tried them. The reason is that everyone is built differently, they have different tonal concepts and goals, they use different reeds (strengths, cuts, and brands - although many are made by the same corporation), and have a variety of horns upon which to play the mouthpieces.
Sorry, but I doubt that anyone who has played the mouthpiece you queried could give you an answer that is pertinent to you . . . only to the ones who've played it. The fact is - you must try it for yourself.
Why don't you find one and play it, then report back to us how you liked it? DAVE
