Yeah, you ought to experiment with the light only on your helmet just to see how it affects your night ride experience. I have gone a bit farther than most -- in terms of the Fenix flashlights, that is -- with two handlebar lights and one helmet light. But my feeling is that the most useful light is the one that's attached to the helmet. I do a lot of riding down very winding paths and the like, and looking ahead into the turns with the helmet light makes all the difference in the world. And even with street riding, having one light on a "swivel" so to speak (my neck and head being the swivel) helps me to light up the things I need lit up, even around relatively easy corners. I think most folks that ride with a helmet light share pretty much the same sentiment. Not trying to talk you into spending more money, of course...
