Copy. Paste. Presto, that's my set up.One thing I do like with the Glowworms is the ability to change the lenses in lights. I setup my 3-LED bar light with two flood beams and a diffuse spot for a mostly spread beam but with a touch more depth to it, and the helmet 2-LED light with diffuse spots for better projection, but with a little spread (which is handy when you hit a switchback and your helmet light is doing all the work). It's a very good combo.
Personally I just use the extra-low setting while climbing most of the time, the low setting is perfectly adequate for moderate blue trails, and medium is heaps of light. Haven't felt the need to run them on high yet, doubt I will either.
Worth noting, the more you diffuse light, the more it's "power" is lost (as it's the same amount of light spread over a larger area), hence running the larger 3-LED with the flood beam lenses for a good balance of light between bar and helmet.
I raced it into the darkness and like Beeb, middle was plenty of light, even at 40km/h down the (straight) fire trail.
