Um, a PB superflash is pretty darned easy to beat. It was a great light 5 years ago, not so much now. It's not really that bright, it's not particularly waterproof, many people have reported having it fall apart when traveling on rough roads, etc. For not much more you can get into way better lights.

I have a Hotshot and a Knog Blinder 4V. I like the Blinder better but the mounting is "seatpost or nothing". The Hotshot is good but the field is too narrow. I'm thinking about buying a few more and playing around. Really I think the deciding factor will be mounting options.
