I chose this pick as I thought it might be more comfortable with my arthritis and it does help. I think its the width of it that makes the difference.
The extra weight to this pick does give it it a nice solid sound when played with. Until you get use to it it sounds like your playing heavier than you are, but you adjust as you play more.
The unbuffed surface does make gripping it easier even when you sweat, so it's not so easy to drop. For the price of these you cant really afford to lose them on the first gig.
