VForce single pane lenses are really good, I've ran them in Profilers and Grills for years. Only this last winter when I played in the very cold did I get fogging and as I needed to replace it anyway I decided to invest in dual pane thermal.
The great thing about the single pane lenses is that they are far more durable and easy to clean that the duals, you can simply whip them out and run both sides under a tap which if you did that with a thermal you'd wreck it..
