I own a righty double version of the 2009 series with the cobra coils and an earlier series single with no coil. they are very good pedals, very light and smooth as hot butter. Obviously the only thing that will make your double pedal skills better is practice practice practice, but cobras will definitely make it feel alot better and make it easier for you to set the pedals to your liking. so i would recommend them, also what kinda music do you play?
