On the money, turf! My SBA alto has the most nimble table keys of any horn I own. The little ramps the tech added make it even better.It's as if, having devised the Balanced Action with its small keys and positive action, Selmer felt they just had to add some more parts and make it sloppier. And then they made the whole thing even worse with the bizarrely hypertrophied keys of the Mark 7, apparently only intended for NBA stars to be able to play comfortably.
The only downside to that design is the long curved bar that connects the C# touch to the rod. There is no positive stop to the key, it relies on the stop of the G# key. It feels kind of spongy at the end of travel. I put a chunk of cork under that curved bar, glued to the body, a positive stop. Feels much more solid.
