The CountryComm mirrors are nice, but heavy glass and large sized....no way are they bottle sized.

You might want to consider switching to PP Nalgene bottles, their mouth will flex by a mm or two to allow a good mirror in I think.

I would not compromise on the mirror in any case. You have taken the trouble to find excellent pieces for these kits so you may as well spring for quality mirrors. Doug's mirrors are quite nice....maybe you just want to add a Ritter Kit to each of these eh <img src="/images/graemlins/smile.gif" alt="" />
