im enjoyed using the DR coateds once, but found that they don't really last long with me, coz i'm a HARD FRETTER, haha and veri abusive to my strings too, and yes tone is in the fingers, so you want more tone, pick harder and fret harder, but your strings frets and picks wear out faster
$18 is too much for monthly expenditure, but now after shredcow has put it, i might consider going back, as i hardly have time to play guitar nowadays
