Just a thought here. Some of you may know that Fender closed their string making operation in Ensenada in 2011 and that their strings are now made for them by D'addario. This doesn't necessarily mean that they're just rebranded D'addarios, but I do notice that the Fender 9050s are now in 7 sizes (4 and 5 string) where there were only 3 before. The sizes in the sets aren't identical to D'addario Chromes, but it makes me wonder how close they are to Chromes.
