P. Red Iridium is my choice overall. It has adequate bright sun protection, while providing enough visibility for ducking into intermittent dark tree shadows on *fast* curvy descents. Of course I'd rather have Black Iridium for our fulltime bright sun, but its scary for the above conditions, so oh well. ymmv


P.S. The big disappointment is the lens outside face is only partly red. Not as cool as could be.
