Is there anything to be settled?
If a drumkit is used by more than one drummer, it's very likely that something might not be to your exact liking, just check the kit before playing, no real issue here as far as I see it
The other user(s) might think the same as you, why do you leave the snares on and hi-hat open?
I leave the kit in the setting it happen to be when I finished playing, snare's wires might be on or off, it depends, but I always check before playing on my next session
+1.I don't do either, and I've never noticed any ill effects on either my snares or my hi-hat springs.
+1 again.But I also don't get upset if I find communal drumkits with the snares off and the hi-hat loosed.
I heard 24 ten thousandths of a second but that was years ago. Things may have improved over time. If the buzz bothers him turn them off. As for lasting longer, Nah. Most snare releases have cams not springs. Leave them onPuresound states on their website that engaging and disengaging the snares shortens the life of the wires by 23 ten thousandths of a second with every strainer release.
