Here is a piece I have kept around for quite some time.  It is VERY VERY great. Tip size at .103 is quite in the middle of optimal for the compromise of power and center. This setup is very close to my personal daily player. It is bright, warm, has focus, but also spread, and an ocean of color.  I would say this is not at all a dark piece, but it is just a hair backed off of the far end of bright on the spectrum just due to the influence of the bog body of sound this one has.

This still has a lot of its original gold plating on the body. While there are always different flavors to be found, in my experience there is no better double ring to be found.  This is the thing and mostly they cannot be found.
