Last year my wife convinced me we didn't need a hub dyno and lighting and money was tight with the camping gear we already bought and on the first night we got lost in the dark. While it was nice to say I was right it wasn't convenient so this year's tour is being prepped starting with a pair of hub dynos for the adults and usb rechargeable lights for the kids. I'm looking at a shutter precision hub as it seems to get decent reviews for a good price along with a Busch and Muller 40lux light. During the day I wouldn't mind the extra drag to charge things and I'm looking at this

to charge the two battery packs I have which will keep phones and USB lights topped up while riding. Will this be sufficent and is it decent or should I be looking at something more?
Secondary question. Are dynamo hubs solid enough to build into the existing wheels and riding with full time or should I build them into seperate wheels for touring use only.
