i like the protection and visibility with E. i have often thought of a detachable multipoint detachable protection for runners and double cabs. just something to cover the rear doors and just use pins at the attachment points.
my vote was for C. for two reasons
I like the full cage (ex. C., E., H., I.[from post #6 ])
and I feel it looks better when the tube near the bottom of the back window matches the angle of the window (in this case horizontal) ex. C., I.(#6 ) :2cents:
