Did you manage to find a balanced 0.40 set?A stiffer G string but the same 040 thickness. The Fodera 040-100 set is more balanced tensionwise in my opinion. But the D'addarios feel nicer and are a bit cheaper, especially before D'addario raised the price a lot (more than 15$ per set I think?) since a few weeks or months ago. I used D'addario nickels EXL170 (100-80-65-45) for all my life and love those strings but I want a thinner D and G now.
I'm looking for a 0.40 set for my Ibanez MC2924 to slightly lower the tension on the neck (currently I use d'addario EXL165SL on al my 4-string basses)
I'm gravitating towards the GHS L3045 set which seems to have a really balanced strings tension.
