Could it be because of the curved arms of the Monster Dogs?
Another thing. The Fasts have very small unobtainium plus the front is heavy for a sports pair since the Switchlocks are stainless. I find running in them a little hard since the weight starts the frame to bounce on my nose. I love my Flaks for running since it's like a feather and stays put pretty well.
yep its the wrap of the frame. and true, FJ's are front heavy.. the classics are way better. the radarlock is all plastic
and best of both worlds
