Our church bass needed some bass strings so I bought some yeasterday,I bought some D'Adderios XL medium gauge,.50-.105. They are pretty stiff and take a while to get used to. Being a guitarist they really rub my fingertips raw,but I don't know if the light gauge would be any better. We don't play the bass maybe twice on Sunday,and for practice and hour and a half a week.So They should hold up for at least six months with normal wiping,right? What gauge do you prefer?
