Thats great.Interesting comparison, they ARE really similar (much more than I would have thought.) In fact (if it were me) too similar to keep both. To use a "Joe/car" analogy...
No need to keep a BMW, Lexus, and a Benz all in the garage. Keep the one that gives you goosebumps, then get a Landrover or an Escalade (for the snowy days,) and a good ol' American muscle car for those "high testoscerone" days. And always keep a Japanese import in the driveway to loan the kids or run errands in.
Please excuse me if the analogy doesn't quite work, I ain't a car guy, but I think you know what I mean. Nice comparison. But if you had put a nice SCDR chimey shank in the comparison, that would have sealed the deal, you can't get THAT sound anywhere else. Personally, I think you were closest to "cymbal happiness" when you had a set of old A's, a set of Bosphorus', and the SCDR set.
Yeah I can hear Keltner putting a bunch of rivets in a Rough and playing it with that big 16" Rototom over his hi hats, or with his kit of all snares and no toms. Love that guy!
No need to check with me. You just check the WikiZEN can tell you when they were introduced
SCDR/Dark Ride is something like 1979?
Rough Ride is like 1989 or early 90s?
