I like the Dunlop Jazztone 207. It's utterly rigid but, unlike the Golden Gate or the Dawg picks, it still has a point (in fact three in various sharpness). One reason I like it for a beginner is that the tone is nice acoustically (I don't play amped) but the thickness of the pick really aids in being able to hold on to it. I like that better than relying on the give of a thin pick to keep the pick seated properly in my hand.

I also flatpick the guitar and so I always use a rigid pick -- in my fiddle tune jam I'd be transparent with a thin pick!
