I used to play 1,5 mm Purple Dunlops in my youth, lots of power metal stuff. I think I read somewhere lately that they were Yngwie's favs as well. And yes, they were great, but these are just a whole nother level. The purple ones were slippery and were worn down quickly by "shredding", but these seem to last forever and the grip is awesome. And the extra pointyness of the tip makes them a wonder to play. I think I'll never buy another electric guitar pick again.
