@mech - so you used to have a 300r, now you have a DZ4. anything you miss about not having the 300r? are you favouring the pairing of an RZ4 with a hotshot (eg hand-grenade & rifle)?
does the RZ4 induce the same change of motorist behaviour that i often hear mentioned with a 300r?
from what i can tell, the RZ4 has nearly even light intensity from about 0-90° off-axis, horizontal and vertical... what i can't find, is what is that luminous intensity...? would be great if you could compare that brightness to the "beam" of a more common light.
mounted on a seat-post, does the RZ4 cast a distinct shadow on the ground? for about how far? under street lighting?
i keep hearing how great the RZ4 is... i'm just waiting for someone who's had a 300r to tell me it's really great and worth every penny
