When I get up to a very fast speed, like 325 bpm in 8th notes

At the moment I can play one semiquaver at 350 bpm.

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.

And someone else mentioned my fingers being stronger then the spring tension. Should I lighten my fingers? My fingers are VERY light at the moment? So then should I add more tension to the springs?

HELP!! AHH TOO MANY VARIABLES!!

I just came back from my holiday, and picked up my tenor with slow springs and high action, leaving the Ferrari (best MKVI ever, perfect setup) in the case: all the issues disappeared!

As long as you do not have an immediate comparison, everything is fine.
Pads need to be replaced when they leak excessively.
