I have a lot of respect for the players & enthusiasts who put together the fine points of the Cymbal Time Lines by looking at stamps, lathing, weight, profiles & bells. This makes sense. Now the time lines are pretty well established. However, drummers who think they are informed by looking at one parameter, & thinking that they can guess how a cymbal will sound, & fit in sonically w/ the rest of their set are kidding themselves. Terms like heavy ,medium , thin, & weight, are too general & crude to be of any significance. Buying a cymbal, no matter how much verbiage & measurement is put into the sale, is always a risk.
As far as transporting & caring for my 28". I always try to keep it horizontal. At home I keep it on a stand as part of my set, & transporting it, I keep it horizontal. I feel the weight is too great to ever store or transport vertically.
