The Gravity Gold Picks hold up extremely well. I have had both Bluechip and the Gravity Gold for a while and I honestly can't tell any difference in edge wear or durability. I honestly think the Gravity Gold is much better suited for electric guitars and hard blues, rock and metal than the Bluechip -- tone-wise. But, I do like them both for different things. I just ordered the Taylor Thermex which are more reasonably priced -- 6 for $12. I don't expect them to be as durable as the Gravity Gold ($20 for 1.0-1.5mm, $29 for 2.5mm) or the Bluechip. But, I don't think many other picks are that tough. I completely understand worrying about losing an expensive pick. Both GG and BC picks are earth tones and not that easy to spot right away. I have freaked out several times after misplacing a Bluechip pick. Still, you might want to have one of each at the house for recording -- if it suits you. I bought several Bluechip picks used. Since, I knew I could re-bevel the edge if needed. I have even bought a large triangle BC pick, used, and filed it into a classic pick shape. GG and BC picks both file and shape, in a manner, similar to aluminum. Even though, the comparison to aluminum ends there.
