I found that to be true with the Super Soft set (40-60-75-95) of Chromes I have used for a few decades, now. Pretty early on I started swapping out the .060 D string for a .055.I run 40-55-70-95-130 on my basses - the 55 D string is much better matched to a 40 G than a 60 is. If you like a 45 G, you should run a 60 D, not a 65.
