Just curious, when can be necessary to change the valve springs?We take as example or depart point a normal-average trumpet player, playing so, one-two hours by day with a reasonable force in the digitation work.
Maybe can be difficult to know the moment of change after so many time playing the same instrument;after longtime there are maybe a adaptation by the player to the more weakest mechanic answer of the instrument valves.

And for the choice of the springs? Is better to use the examples copper coulour or the stainless steel versions? There are big differences between this two types ?Certainly they are some differences in the metallurgic and the mechanics factors of this materials.

Thanks

Daniel
