I previously used Dunlop Big Stubby picks but I found them to be too noisy against the strings when I play. I ended up getting a Fender celluloid pick and using that for a while, but then when I got a few variety packs to experiment I ended up finding I like sharp picks the best. I found the Dunlop Tortex Flow picks to be some of my favorites, and I also really liked the Hetfield Black Fang, though after playing with the Flow picks for a while and getting used to them I found the shape of the Black Fang to start to feel a bit awkward. I was very excited when I saw Dunlop was releasing a new Hetfield pick but with the Flow shape. I didn't order them immediately but I eventually took the plunge when I had a few other things to order along with them. They are pretty much just as great as I thought they would be. Both the Black Fang and White Fang are made out of Ultex. Two of Dunlop's main pick materials seem to be Tortex and Ultex. Normally Tortex seems to be very matte in feel, while Ultex is normally a bit see-through and feels more slippery. The Ultex the two Fang picks are made out of are completely opaque, though, and to me they feel more matte like Tortex, so I'm not sure if that is something to do with them being opaque or if it is just something with my perception. The White Fangs have slightly beveled edges compared to the Tortex Flow or even the Black Fang picks. I had found I liked beveled edges on picks like the Fender F-Grip and Ernie Ball Prodigy picks, and the beveled edges on the White Fang also helped make them smoother, faster, and more accurate to play with. With the Flow design's wider shape, they are also pretty good for strumming. Rounder tips in general I think are better at strumming, but the Flow design in my opinion is a great all-around design with a focus more towards lead work. I also really like the extra grip on the White Fang compared to the Black Fang, which makes it feel more comfortable and easier to hold onto. My one complaint about these White Fang picks is how quickly they get worn. Two of the pictures I have included are of a White Fang pick after about a month of use (I play about an hour a day around 4-6 days per week) on the left and a fresh White Fang on the right, and the tip is noticeably less sharp and the graphics have started to wear down. The tips of the Tortex Flow picks generally get a bit shiny after a month but the graphics generally don't wear down and the picks don't become that dull that quickly. However, they are still usable though they don't feel quite as nice and fast as when they are fresh, and considering the White Fangs are only about $1/pick (especially if you buy them in larger packs), even if you throw them out after every month it will still only cost you about $12/year to have some very nice picks.Overall, these picks are currently my favorites. I have attached a few pictures comparing the White Fang to some other picks I like, including other Flow picks and the Prodigy and F-Grip picks mentioned earlier. The two picks that come in second and third place for me currently are the Dava Jazz Grip picks in delrin and the Tone Cat picks. The Dava picks are a very close second and feel very similar to the White Fang, though I particularly like the delrin ones since the gel and nylon versions feel more slippery even with the rubber. The White Fang are slightly more metal focused in my opinion and the Dava picks are slightly more rock focused, but both could be used for either genre. The Tone Cat picks are a distant third. The thickness of the picks is the main detractor since it feels harder to move them around quickly, however the thumb indentation is nice which makes them more comfortable and though they look considerably less pointy they do not feel considerably less pointy. They seem good for jazz which I do not play a lot of. I would recommend checking all of these picks out, but especially the White Fangs. James Hetfield clearly knows how to design picks considering how good even the Black Fang was, but the White Fang is a big upgrade in my opinion, especially with Dunlop's (in my opinion) improved Flow design. Now if Dunlop could just figure out how to make the tips and graphics of these White Fang picks not wear down as quickly, these would be even more perfect. So go and buy a pack and rock on!
