The shortest scale dulcimer I make is 24". I use 12 12 14 22 strings without any problems. The nice thing about short scale dulcimers is tuning to pitches much higher then Dad...Robert 

If you want to go to lighter strings on a 23 inch VSL, I suggest 0.011 for the melody strings, a 0.015 for the middle, and 0.023 for the bass. You could always try going down once size on each string to see if it is too floppy. For the most part, experimentation is what you need to find the right strings for you and your dulcimer.

With a 23" scale, you'd have to use somewhat heavy strings to keep the DAd tuning from being too floppy (especially for the middle A string). What gauge strings did you put on it for that tuning?
