Ive been using these for about 5 years now. There's just no beating the high end response and clarity, even a month after putting them on. I used to change strings every 2 weeks ( apparently my hands corrode strings very fast, even with cleaning after every use)
Pros: Improved response in high frequencies
Improved overall output
After initial stretch they hold tune perfectly
Dont seem to corrode as fast as nickels (about twice the life)
Cons: price
Different (not at all bad) feel
All in all a very nice set of strings, worth the money in my opinion, if for nothing else, just to push your amp just that little bit more.
