Strings wise I have settle on relatively lightweight D'Addario nickels in 45/60/80/105 (bought as singles to get the tension I like) on the headless Border Reiver. Having tried D'Addario EXL160BTs (50/67/90/120) I found them to be a bit too heavy for me so the Finn P is now wearing black D'Addario ETB92M tapewounds (50/65/85/105). These are a standard issue medium scale set and work rather well.
At some point I might well try a set of my normal use long scale D'Addario EXL170BTs as I reakon long scale strings on a 32" scale bass will work just fine.
@AndyTravis you are welcome to come round to try them out as we are pretty close to each other, or I'll bring them down to you if you promise to make me a cup of tea
