If you can handle a true .125 more power to you. I like my 'King Curtis' which is .116 for the exact same reasons you mentioned. Yes, it was bright and brash when I first got it but after starting to use it regularly it began to 'come in' for me. These can be great mouthpieces if you get a good one. The only difference in a 'King Curtis' and 'Super King Curtis' is the SKC is bigger. It should have the throat ring filed down flush at the bottom and forming an oval. The later ones also have a more squared-off window. BTW, not many were marked 'SKC'. Dave had to stop using the name 'King Curtis' because whoever owns it wanted royalties. After that they were simply 'King' and Super King'. So when he decided to add the 'Super King Curtis' to the line-up he had only made a few when he had to change the name. I bet the one you have is a killer! If I were buying it, I think I would keep it regardless - its got to be worth a lot and it will increase in value.
