Traded in the superflash for the cygolight. That cygolight has too many buttons and features, but I'll get used to it.

I had a Blackburn flea (but I haven't seen it in about a year - hmmm), and it wasn't nearly as bright and noticable as the superflash turbo or cygolight. The front light needed to be recharged after being used an hour on flash, but the rear lasted much longer (5-10 hours?).
