I too bought the Superflash, BUT the Superflash only strong point is if it's seen directly from the rear, the more off axis you get the less light there is visible to it's completly gone. The LD600 may not be as intense when viewed directly but it continues to be bright all the way around to the side of the bike...something the Superflash fails at completly. I use the Superflash on the seattube and 2 LD600's on the stays.
But the poster wanted to use only 1 light thus in that regard all around performance for rear and side visiblity is cleary won by the LD600.
