Got two dyno light setups are the mo.
Commuter: Alfine dynamo hub + B&M Cyo RT Senso Plus front, Philips Saferide rear
Winter/Audax bike: Shutter Precision PV-8 + B&M Cyo Senso Plus
I love it! Not having to worry about charging batteries on the commuter is ace. Plus not having to remove the lights each day when I lock it up at work. The Philips Saferide rear is pretty cool – had quite a few people comment on it, both cyclists and pedestrians. A dyno setup is definitely the way forward for no hassle commuting.
The Cyo’s have a standlight so stay on for 2 mins when you stop, hence works in traffic.
Got my Shutter Precision direct from Taiwan (on ebay), supposedly its what the USE hub is. A lot lighter than the Alfine dyno hub.
I think there’s a new B&M light out which is brighter than the Cyo; worth a look if your buying now.
