I've got helmet and bar Ayups, but after using them for a year i'm thinkng i would like a bit more light.

I was considering putting a wilma on the bars but then wondered about just buying an additional light head and 3 hr battery and putting it under the bars. The llights and battery weigh 150g, so i'd only have 300g on the bars in total, and have one light head underneath and one light head above the bars (plus the helmet one)

I know its not the neatest solution, and still wont match the Wilma power, but its the cheapest!!! Anyone esle boosted the ayups like this? Does it give much improvement?
