More lighting is always a good idea if it doesn't blind anyone.
That's why I went with the low fork-mounted LEDs. If I lived where there wasn't much traffic (or raced the Dakar or something) I'd have high-mounted lights, but here in Virginia there's a lot of on-coming traffic all the time. The Clearwater Lights "Glenda" model also have a cool feature in that you set the output on low beam to whatever you want with a rheostat switch, then when you switch to high beam they automatically go to 100% output. They are VERY bright on full power but not retina-burning when tuned lower.
I'm not so sure about all this weaving business... If it works for you that's great, but I think I'll stick to less dramatic methods of conspicuity. With all the traffic here I'd be weaving like a drunken sailor every inch of every ride.
