I have a few different ones, depending on what style I'm playing.
Berg Larsen 110/? can't remember the bottom number- currently packed away as I moved this summer and haven't played it since. USe for competing with amplified instruments, especially rock, funk, and sometimes electrified blues. Bright, edgy sound, okay subtone, Good altissimo, projects well with a "progressive" sound. Used with a La Voz Medium or Medium Hard reed (MH was usually filed down a bit) and stock BL ligature.
Sugal Super Gonz II - great all around mpc. You gents in the UK may or may not be able to get a hold on one of these, though. Huge fat subtone, sensitive even at very extreme volumes. More "traditional" sound with a slight tinge of a modern influence. Good for big band lead tenor, session playing, jazz combo, and even for electrified blues. I use a LaVoz Medium Hard reed with the stock slide-in-track integrated ligature. Experimented briefly with a Rovner, but didn't like it. The blue/silverflecked epoxy on the teethpatch on top of the beak flaked off completely. I bought some LocTite clear food-grade epoxy and replaced it. First roughed the patch area up a bit. Even better than before, as the new epoxy has a slight bit of cushion to it. No problems in the three years since then.
I also have a Lawton 7*BB in Stainless Steel/silverplate for my alto. It is very good, and since a lot of pros use them (one I know in Nashville, TN particularly) I imagine they must be quite good for the tenor as well. I also heard the Geoff Lawton passed away sometime ago and the future of the company is in limbo to an extent. For quite a while, the Lawtons have been somewhat hard to get in the US. Lots of distributors liquidated their stock and don't carry Lawtons anymore.
I have owned an Otto Link 5* for tenor and loved it. I only got rid of it because the Sugal did everything the Link did and so much more. Still a fine mouthpiece in my book, and definitely easier on your wallet than the $400 (US) for the Sugal.
Cheers,
