2mm, single round hole, master finish. Tripp Standard for rhythm. Sunrise Big Mini for lead. Honing in on the shape and size was a the biggest hurdle and I'm glad I could afford the variety pack to get to where I am now. I so wish someone had put these in my hand when I was just getting started. No telling where I would have gone. Never expected a couple of picks to open my eyes so wide after 50+ years of never knowing. When you know you won't lose your grip on the pick, other things become so much easier to focus on. My hybrid picking is much improved since turning to Gravity and picking in general is so much cleaner. Now that everything has clicked into place, I fully understand the love people have for their Gravity picks. This is the fourth order sent to me in Germany. Arrived in less than three weeks with the Christmas and New Year's holidays to account for ... plus a snowstorm. Super nice job placing the custom image sent. Definitely worth an extra ten bucks. I've got about an hour's worth of playing time on these so far. They make the clearest/brightest sound of any picks I've played with.
