At the moment I can play one semiquaver at 350 bpm.When I get up to a very fast speed, like 325 bpm in 8th notes
Seriously, I have a similar issue about springs. Some of my horns are wonderful (SML) some are slow (Dolnet). I have the feeling that the "quality" of springs is more important than tension. I hope some repairer could enlighten us. I remember someone heating springs till they are red and cooling them in oil rather than water.
