Strings for a Short Scale
Also, despite what I said about liking the DR Sunbeams at the end of that thread, I ended up switching to D'addario Chromes after a week. Just couldn't get used to the DRs' low tension on the short-scale bass. I asked DR if they were planning to come out with a short-scale version of their Lo Rider strings, but unfortunately they said no.
The Chromes are pretty amazing. And I did buy medium-scale strings, as recommended by D'addario. Short-scale D'ads would not fit my string-through bass.
