If possible, use a bag or case with cloth dividers to prevent scratching.
As a general rule, larger and thinner cymbals are darker and have a lower perceived pitch. Smaller or heavier cymbals tend to have a higher percieved pitch and are more able to cut.
Even a slight tilt of your cymbal stand will make a substantial difference.
Allowing them to move more freely enhances tone, projection and durability.
Always use sleeves and felts on your cymbal stands.
Doing this will simplify the cleaning process later.
