every track i have ever ran with lugs less than 1" as been installed in the reverse position. always noticed a positive for traction, never felt the breaking issue but was always forwarned. i can see where the difference may be noticed in given snow conditions, but never knew the difference for the conditions we ride in.
up until the my tracks exceeded the 2" lugs is when i paid attention to the arrows. the taller tracks are more directional specific.
