Really like you video review Alan, I to am a big fan of what the Sunglass fix offer in regards to replacement lenses, I highly rate the quality and clarity of all the lenses I have obtained from them, and most of my lenses bought through them are mainly for my Tail series also.

The Blue/Purple ultra SFx lens is also another great lens and also can be found in both non Polarized and Polarized option. It is Black lens so quite neutral and just deepens the colour tone of your surroundings. It runs the same Percentage of tint as nearly all there lenses on offer so the vlt would be 15% aswell.

I have these in one frame as well Sikpup Really enjoy that lens too.
