Hi, I just bought a 5-string Brice Defiant. I want to know what string gauge I should get because I am setting it up to tune to drop A flat. I think that .130 is too light and .174 is too heavy (I have a .185 that I tune down to F# on my other bass). Any suggestions? And for the other strings, I was thinking something like .105 to .45. Would this work?
