There's still this skepticism when it comes to treated strings, that chemistry affects tone. Whatever the case, it doesn't prevent me from trying. Thusfar, the Acoustic Science brand offers the most unobtrusive presence in terms of feel. It is quite the other end of the coated treatment we often encounter with coloured strings. This re-string was done last weekend so over a 5-day period, it's rather premature to offer any conclusions in terms of performance but I must say that the feel retention is impressive. The Science of it all is this- the manufacturer modified the string surface to be more resistant to whatever present themselves in degrading the string material. So far so good.
By the way, 'acoustic' here does not refer to acoustic guitars exclusively. Some people whom I talked to recently thought these were acoustic strings but that's the consequence of not reading the literature.
Acoustic Science strings are available at Davis GMC.
