After getting hit in daylight (right hook, while passing stop-and-go traffic) I'm now riding with a NR MiNewt 600 Cordless for my daytime commute (flashing). I opted for that so I could be seen in daylight, and still have my other rechargeable lights available for the evening return. At night I'm using the 600 a bit too, but I'm moving away from using it on the flash mode and feeling more often that the walk mode is enough for were I am. I've also got a NR MiNewt X2 that I use for night riding, but I'm now having a conflict with it's cord getting detached while I'm riding (bumps the 600's mount). Still looking for a solution to that issue.
