I can't seem to grasp playing chords well, for example:


|G|--11----9----11----7-----------------------|
|D|--0-----7----9-----5-----------------------| 


from Blink 182 - Carousel.

I use a plec to play them but I can't seem to strum up and down quickly.

Any advice or techniques on how to play these better?

Well, personally I hate playing chords all together, but when I do, I use my fingers. That's just me though, but as far as speed goes, there's not alot you can do just keep going through it and speed will develope.

Learn this Don't Forget me by the Red hot Chilli P's its got a pretty simple and down-tempo chord pattern which should help you practice.
