Thanks for the feedback. I'm now using a Dinotte 140 as well as a couple PB Superflashes. The Dinotte is incredible but hard to mount and swap between bikes, and the battery pack adds a lot of weight. I tried the new Light & Motion Vis 360 but it doesn't seem as bright as my Superflashes and the battery run times were disappointing, so I returned it. However, I like the helmet mounting feature and chargeability, so the Red Zone 4 looks promising in that regard.
