I'm glad you read something that helped with your decision. I read mostly about nighttime visibility and non-relevant opinion. One poster said a narrow beam is excellent for daytime visibility, then later the same person says a broad beam is better. I would like to read an objective report if you could take the time for an update on your experience. Have someone watch your bike at a distance, top of the hill, bottom of the hill, while in a corner, etc., and share the feedback. Bike movements are too dynamic to rely upon straight-on evaluations. Lately I've spent time at a large city MUP observing bicycle lights at day & dusk and poor off-axis visibility was apparent.
