Anyways, my point here: all this will get out those tiny down-like hairs (possibly some others too) and really lessen the bulk of the mane. Pulling would be ideal, but in a short amount of time, this method helps partially. Again, after a workout would be best and not slippery conditioned either.
I have combed it the other way several times after I've ridden her and it helps a little. I know she doesn't mind if you pull her mane for too long but I know the way her mane is it will take way longer than I've ever made her stand for any amount of braiding or grooming. To answer how thick and long her mane is, it is about 7 inches long and thick (not anything like a friesian) but with mud and dirt from being outside all the time. It sounds like I'll have to comb, cut, then pull. I have wednesday and friday to try and get her ready. I never was expecting to go to a show this early but its experience for her so I got pushed into going last minute. Thanks for all your good advice it won't go to waste.
