I don’t know the physics of this but years ago I used to think bigger fatter strings would give me more bass but I don’t think this is the case , I went through so many different ones trying to find the right ones for me, I only use 2 now which are labella LTF’s and labella 760FL , I wouldn’t say I got a stronger sound from the heavier gauge ones just a different sound, I play with a very light touch and never dig in, the hardest ones I found were the Jamerson flats, nice sound but pretty high tension, try as many different ones as you can and you’ll find the right ones for you
