Has anyone tried the transition lens for mountain biking? I wonder if the transition is fast enough to compensate for the constant changing light on the trails between sun and shade. I currently use a clear lens which is a happy medium between light and dark conditions.
I'd have to agree with Herbsley, I've used both the high intensity yellow and clear for road racing and mountain biking. In the end I always ended up using my clear lens as my standard non-sunny day lens mounted to a Pro M frame.
