the reigning champion in self-contained rear-lights, the dinotte 300r
has anyone done a side-by-side with the niteflux red zone 4?

i wouldn't expect the RZ4 to be as bright as the 300r, but from what i can find the RZ4 may be better for city riding while the 300r may still be the king of the open road.
another small detail that favours the RZ4 is the smooth finish, which should shed crud better than the 300r's ridged finish over the lenses.
i'm kind of thinking that the RZ4 would be hard to beat, paired with a hotshot or moon shield/serfas TL-60 (as one reviewer called it, the rifle and hand grenade approach). but i can only tell so much without having the RZ4 or the 300r in front of me.
