I am a long time user of the Ernie Ball Classic/Rock & Roll sets.

I wanted to try, for example, the new Turbo set with the slightly lighter gauge unwound strings.
My question is whether the *unwrapped* strings from the normal nickel plated sets are made of the same materials as the unwrapped strings from a Classic/Rock & Roll set. If so, I should be able to make a "Classic/Rock & Roll" set by swapping in the unwound strings from the Turbo set for the unwound strings in a Classic set, correct?
