I have been looking at lights for about a year. The Fenix flashlights were an interesting option. I saw a thread on Roadbikereview.com that a guy was using a Black Diamond Icon and also recommended the Princeton Tec Apex headband. He was supplementing his Light and Motion Vega which I also have.
I was still trying to decide between the Princeton Tec Apex or to with a cycling specific. Cateye Tripleshot or Light and Motion Solo MV - Li-ion were heavily discounted at Nashbar and there was also an additional 20% coupon that would have brought these lights into the $165 to $180 range delivered.
But for some reason I kept looking. I found the Princeton Tec Switchback 3 on closeout at Colorado Cyclist for $219.99. They also have the Switchback 1 for $119.99. The thread today compared the Fenix to the Switchback 3 and it appeared the Fenix is close to the Switchback but I think I will like the superiority and convenience of the Switchback. It is scheduled to arrive on Wednesday. I will test it and give my humble opinion sometime next week.
