I've been reading quite some about bike lights in recent days, and the more I read the more confused I seem to get. So I figured I'd ask some bike fanatics here on advice. I'm looking for rechargeable bike lights (both front and rear) that combined cost 40-60 pounds and each around 15-30 pounds. They will be used primarily as be seen lights, but a couple of nights a month they will also be used as "to see with" lights on somewhat dark trails in the countryside.

So far i'm thinking of either the blackburn flea 2.0 usb set or the knog boomer. The flea would probably be best but i'm afraid the velcro strap thing will weaken greatly over a few months. Has anyone experienced this?
