I haven’t used flat picks in almost 25 years of playing, and have tried pretty much every thick contoured pick that is available on the market. Above a certain thickness, most of what’s available is extremely expensive, and made of “exotic” materials that are prone to breakage, and don’t hold a sharp tip well. Gravity’s 6mm acrylic is about as close to indestructible as you can get and cost a fraction of what most custom pick makers charge. For a totally made to order pick tailored to your own personal specifications, you won’t find better quality, service, or price point. Took three business days from placing my order to picks in my mailbox. Doesn’t get any better than that. 🤘🏼
