for about 8 years i used 1.5mm green dunlop gator picks and liked them so much i never committed to any other pick as much and I've tried about 15-20 other picks. Various materials and all. These 1.5mm flows to me are better because of the added grip and subtle bit of extra slipperiness the flows provide. I may try the 1mm ones next just to see if i can get a bit of extra brightness but the 1.5mm ones I love the translucency of the dark red as my guitars just happen to be red and its practically the same shade for the most part. The tone is similar to the gators or flex picks of similar gauge. Dark, loud, lots of mids. I like these way more than the john petrcucci and andy james ones.
I'd buy them again in a heart beat
