Intial impressions are pretty surprising. I figured for sure that I would notice the "flat" part more with my plucking hand, but I definitely feel it more in my fretting hand. Very nice to have that smoothness under my fingers tips for slides, and the slides are super clean sounding.
Sound difference is not quite as dramatic as I figured it would be either. It not rounds but again just not as big a difference as I was guessing.
Granted I am still setting the action/intonation so I haven't spent a long time with them.
Bad news: I cut the E-string too short

Anyone know where to get a 100 single? I did find one on Amazon for $17.45, but I'd like to consider other sources and if necessary just go back and buy another pack so I have some backups.
