ive used the original deathadder v1 since release, 6 years~? baught a 2013 edition because i can, tried it out, its exactly the same, apart from that its alot harder to pickup, the whole thing is made of cheaper plastic or rather plastic that has a matte finish, and because of this matte finish it is slippery as, i have big hands, i rarely sweat, i play claw style, i also pick up the mouse mainly with the sides of my palm inward gripping the outside edges of the back top part, u can do this very easily on the original deathadder cause it has a rubber coating, however u cant do it at all on the 2013 edition, also the rubber on the sides of the 2013 edition actually makes it harder to pick up with normal dry hands compared to the gloss plastic the original has, gloss plastic is alot more grippy if its not covered in so much sweat that its dripping off, and like i said i rarely sweat, so in other words would i recommend u upgrading? no because its way too difficult to pick up, i run at 400dpi, 6/11 windows 3-3.15 sens, hybrid wrist arm, 2.5 arm 3.5 wrist....
