Just throwing this out there. If you want to replace the polycarbonate lens on your Peak Pacifics order the 17.7mm x 1.5mm mineral crystals from this site http://www.ofrei.com/index.html. They work perfectly in the SSC models of the Pacific and require the front of the reflector be sanded down a little for the old Lux III models. I like having a little extra thickness up front although the standard 1mm models would probably also work. They're 2.50 each and minimum order quantity is $15.00. If anyone wants to go in on some with me, I wouldn't mind having some backups. I actually have some of the 17.8mm x 1.5mm (2) and 17.8mm x 2mm crystals but they're just a hair too big.
