Didn't change my picking speed, still working on that but I found that Dunlop picks were pretty much good for nothing after a couple of pick slides, whereas the d'addario ones seem to be a harder compound. I can slide all day and still use the pick after... They also have a logo etc moulded on each side, which makes them less prone to slipping than I found Dunlops.
Might just be me... If I ground my pick tips to a point, I'm pretty sure my string bill would go through the roof....
