Got sore finger tips?  Recovering from a long absence of playing...?  OR like me...you were playing but had an injury that kept you away from your guitar for a while and your finger tips went soft again??  These strings are definitely worth getting.  I injured my shoulder and just couldn't pick up & hold my guitar (Seagull Rustic Acoustic) for weeks & weeks... by the time I could play for even just 10 - 15 minutes before my shoulder would start screaming at me... my poor finger tips were screaming as well from the heavier Martin SP's I had on.  So to get me back in the grove and toughen up the tips a little... I got these and put them on.  Finger pain not an issue now.
