TLDR: If you've played guitar for more than a year, you _deserve_ a custom made pick. Find one that suits you as early on as you can.
Gravity picks are the best I've owned in over five decades of playing. And, imagine, I got my first Gravity picks as case candy in a new guitar purchased from Sweetwater only just last Christmas. I'm comparing these to my ol' Jim Dunlop Max-Grips and two different BlueChip offerings. Took me about two seconds to realize I favor the picks with the eliptical hole. Thumb and forefinger naturally put the pick's tip at the perfect angle to work the strings. I bought a "Filled Box" and Chris let me choose the exact picks going in there. My order was complicated, but filled perfectly. Thicknesses from this order were 2 to 6mm. BlueChip 60s feel like they're 1.5mm. The Classic XL Gravity is also practically the same size as the TAD-1R. The first time I rubbed TAD-1R across the strings of my acoustic I was left grinning ear-to-ear. The Classic XL 2mm with the Master Finish sounds even better. I didn't think I'd care for thicker picks, but they're easy to play and sound so good. I've no idea which one(s) I'll reach for. It'll likely be the polished edge for electric though.. Also, I live in Germany. These picks were ordered (free shipping through USPS to the APO) on the 29th of July and arrived on the 12th of August. Looked like delivery was slowed by Customs, but the packaging had not been opened and re-sealed. Overall, quite happy so far. Jam-On, People!!
