If you live in a climate where winter provides more active riding days, where faster work or jumping might be possible, choose this clipping option. Start as per the low trace clip, but swing the line back from a much higher point—from midway down his shoulder, back to a line that ends about half-way down his hindquarters. (The line will hit a level that’s about even with the bottom of your saddle flap.)
wish a picture was included like there is for all the other types of clips
good info
A picture of the Medium Trace Clip would be helpful.
