In trying to put together a balanced set Chromes by buying single strings, I'm finding discrepancies between the tensions listed in the official tension guide and the tensions listed in the Chromes section of the D'Addario website. I'm considering going with either 40-55-70-95 or maybe 40-55-75-100. I notice that in reading some posts about balanced Chromes, people are choosing their strings based on the numbers given in the tension guide, but those numbers might be inaccurate. The website gives the following tensions in pounds: .040 = 37.8 .055 = ? .070 = ? .075 = 42.6 .095 = 36.2 .100 = 40.3 The tension guide gives the following numbers: .040 = 37.6 .055 = 36.6 .070 = ? .075 = 36.4 .095 = 35.2 .100 = 38.4 While the numbers aren't terribly different, they are different, and I'd like to know which set is accurate. The difference regarding the .075 string is considerable. Also, the chart does not tell us the tension of a .070 string when tuned to A, but it does give us a tension of 107.3 lbs if tuned up to G. That makes no sense. I was going to send D'Addario an email but they want you to give them your full name, full address, blood type, and social security number if you email them, so I thought to post here in hopes that Jason or a D'Addario rep will see this thread and answer my question. Thanks in advance. P.S. The tensions listed on the website for the 5-string long scale set incorrectly match those of the super long scale set.
