Knowing the cymbal's weight might have helped you make an informed decision. If I owned a drum shop, I would gladly weigh cymbals for remote buyers. Online retailers such as Sweetwater and Musician's Friend should offer this service as well. Customer satisfaction means fewer returns. Everyone would come out winning.One and only time I bought a cymbal unseen was an 18” A Zildjian Med ride, my friend’s sounded awesome and this was the clunky-est hunk of metal ever. Cymbals are way too variable even with modern purchase methods, I need a connection before purchasing which can really limit selections. Drums are different I feel.
Note: I know that weight alone doesn't determine a cymbal's sound, but it's a very useful metric when buying from afar.
