I have used my $40 ones for 3 years on my road glide. The frame snaps are a pain. I have found that putting them on the night before and not snapping the frame part allows for streaching and easier to complete install next morning. The upper engine guard snaps inside the fairing support so I have come to not bothering with the frame snaps.
My feet actually get almost too warm from 47 degrees and up. I always remove the lowersabove 58 or so.

 

The $60. HD won't stretch as much as the vinyl. JMO

 

Woah! This is an old post. Mine, in fact. I'm good to go with the $60 ones last spring...
