So been reading about these for a while and figured I'd give them a try. First thing I noticed was no felt/twine wrap on the ends...Does it make a difference? Couldn't tell you but it is an extra step in the manufacturing process and shows attention to detail and less potential to mar your metal so there's that. Got them on and winding up I barely notice any shimmer. You know, the almost chime like quality you from new strings? So that was another red flag. Got them tightened up and these things are pretty dull, no real brightness to them. If that's your style, great...It's not mine. The E string is pretty dead and the G string was very loud, very inconsistent tonality. I guess all this is to be expected from strings coated in some gunk from the manufacturer...I'd rather enjoy bright strings for a few weeks with a gradual taper off than flat strings out of the package...that'll stay flat longer. I typically play Dean Markley, Blue Steel and these are for sure no where near those in terms of brightness and quality. These sound like 3 month old Blue Steels. Total bummer...Your mileage may vary but I'm getting off at this stop and going back to what sounds good, to me.
