If you go to Kalium's web site, they have a tension calculator, so you can pick strings that make up a reasonably balanced, or even a progressive tension set - and you can get strings in a myriad of diameters. I myself play a 37/51/70/95/130 set (without the 130 for a 4 string), which I find to be suitably soft and twangy - I've had wrist issues, which drives me to that neighborhood, and I also like the growl and clank you can get from a very light set. You can go much lower than that with their strings, should you desire, but at some point, you'll get to where it's far too easy to clink and clank - only you will know when you're at that point.
