I think I'm going to get a Trinewt for the bars and use the minewt on the helmet.
I tried this Minewt/Trinewt setup for the first time this morning at Lewis Morris. I had previously used the Trinewt on my helmet, but it felt soooooooo heavy, especially at the end of the ride. I didn't even notice the weight of the Minewt and battery on my helmet because the weight is more distributed. Having the Trinewt on the bars might have been overkill, but when it comes to lighting up the woods, more is better, right?
