I'm not worthy ... I'm not worthy *bowing and grovelling in Wayne and Garth fashion to the mirror master rafowell*

Seriously though (and this is a serious topic after all) I am seeing a lot of mention of 2" x 3" signalling mirrors. IIRC Doug Ritter stated that the reflectivity of the mirror is a function of its size. That said, I certainly hope everyone's dedicated signal mirror is larger than a 2x3. Granted it is extremely small, light and easy to carry but given a choice I would opt for a larger 3" x 5" or possibly a 4" x 6" for my main dedicated signalling mirror in a larger kit or pack. Or even in a pocket. I thought the smaller 2x3 was supposed to be a backup to your larger mirror but it appears that several people have turned it into their dedicated main signaling mirror. Not criticizing or belittling anyone here. Just want to make sure everyone is giving serious consideration to their signalling devices. I'm not an expert by any means just my opinion based on what I've read and learned thus far, mixed with a little common sense and stirred frequently over high heat ...
