I am currently using the Proto switch FS goggle but after a few issues with fogging and just wanting to upgrade I have been looking into getting a new mask. I really like the look of the V Force Grill and know they are a popular choice. My only concern is that they don't come with a thermal lens as standard, so I wanted to know if the standard single pane lens is any good? I realise they now do thermal lenses but don't fancy buying a new mask and then having to purchase a new lens straight away. The Proto goggles I use have a thermal lens and even they fog up occasionally. Also any other recommendations would be appreciated. Cheers
