If you're looking at 4 strings, I'd go with 45-65-85-105. That's the most in the middle. I'd say if you're using a pick or fingers to play, then heavy gauge will work, but if you want to play faster or play tapping or slap, then better to go with light gauge strings. Still, light-medium gauge is probably to best to start from.
Also, if you have 5+ strings it makes a difference. I have a 6 string bass and the gauges of the strings are 32-45-65-85-105-145. If you think the 145 B string is ridiculous, I agree. But with many basses that have a neck below 35 inches (including mine), a light gauge B string will just be too flabby unless you tune it up to E (which is actually quite nice on 5 string (EADGC tuning) but on 6 string the highest string would be too tight). I'd say a B string should be above 135 gauge, just to be safe.
Also, there are lots of websites (like Bass Strings Online, and even Amazon) where you can order individual strings. So you can mix and match them to your liking.
I hope this helps.
