DR Sunbeams, eh?  I'll have to give them a try.  I've been using Alembic strings on my Signature Deluxe Superb Walnut 5-er, but I recently bought a GK MB 112 -II, a matching extension cab, and almost immediately found the Alembics to be just too zingy and bright.  Then I switched to D'Addario Half-Rounds, and like them a lot better.  Still trying different things, though!!

I tried High Beams. but they were a little too bright. The Sunbeams seem to have a richer tone.
 
I use D Addario Pro Steel's on my Series II Europa & love them, but I haven't tried them on my SCSD.
