I've actually played all those mouthpieces, if i were you i'd go with the berg larsen, but here's the deal with those, the best ones and most popular are the SMS series, these things are awesome, but you're gonna want to get one thats really open to get the most out of it, the most open is the 130/0, the 130 is the tip opening and the 0 means it has a high baffle, the baffles rate from 0-3 0 being no baffle, and the tips gofrom like 80 to 130, by 5"s, the more open ones are the 120, 125, and 130, FYI Lenny Pickett from saturday night live band plays a 130/0 SMS. Unfortunately theyre almost impossible to find so youll have to order it directly from Berg, and it'll take about 6 weeks and cost around $250. I also have a beechler bellite metal, those things are great mouthpieces too, mine is a number 9 which is the second most open, the have a really powerful in your face sound, but the response in the lower end and the altissimo isnt too great at first so i had mine refaced, i cant stand otto links personally, everyone ive played just didnt appeal to me. I personally like the berg the best the response is great from low Bb to G4 and it's powerful. Stay away from the M's though, those ones suck, get the SMS, Another mouthpiece you should consider is the Dave Guardala Studio, which is expensive, $300-$400 for the laser trimmed depending on where you get it, and up to a $1000 for the original handmade, which are no longer made, this one is popular because it's the one Michael Brecker plays, no need to say more about that one.
