Berg Larsen 110/2 (I've got both an grained ebonite and a Steel (can't bear to get rid of either) with Rico Plasticover 2.5s, Vandoren V16 2.5 or LaVoz Medium (or occassionally a Rico Jazz Select 2H or 3S) for tenor. Great set up for blues, R&B and, well, general noisiness.
Soprano- Yanagisawa ebonite 7 with LaVoz medium (not really got into experimenting with soprano set ups- As the little sods are so tricky to play anyway I've always played safe and taken an 'if it ain't broke don't fix it' approach).
Soprano: Dukoff D6, LaVoz MH or Vandoren V16 #3
Alto: Dukoff D7, LaVoz MH or Vandoren V16 #3½
Tenor: Rovner Deep-V #8, Plasticcover #4-5 (bari) or Dukoff X8/D8 LaVoz MH/H or Vandoren V16 #3½-4
Baritone: Dukoff D9 (tip open up to c 0.140" and baffle slightly taken down), Plasticcover #3½ or LaVoz M/MH
I decided to use the same mpc, type of reeds and type mouthpieces to make it easier for me. I also use the some saxophone brand/model except for my soprano. I couldn't resist trying a Rovner Deep-V tenor mpc the other year and since then I'm stuck. I'm not playing that much soprano, alto and bari these days. On my other and older saxes I use the original or simular mpc-reeds.
Alto - Martin Indiana and/or nickel plated Conn 6M VIII with ebonite Lawton BB 8* or Jody Jazz HR*7 both with Fibracell soft reeds
Soprano - Lafleur (Amati stencil) with Bari .58 mouthpiece and Fibracell soft reed - not found the perfect sop set up yet..
