Yeah, so... I think I would keep it forever. There are very few cymbals on the market now that I would be able to replace it with.
I like some of the K Custom Dry/dark stuff... but since I only paid $50 for this and it should last forever, if I take care of it, then I don't see any reason to unload it for something modern. I would maybe consider trading it for a similar one if somebody had something that was a little dryer with a tad less low-end build-up. But otherwise this thing is the ****.
I'm still on the fence about having it "worked" on (smoothed edges, slightly enlarged hole). I know value means something to you guys but this thing will be played and probably be the only ride I own for a long time (I'm not a serious drummer, really a bass player that dabbles).
Anyway...
