One thing I will say though, if you are working her uphill, be sure to work her downhill as well or she will end up lop-sided. When I was a youngster, we rode our horses on a ski-hill. I was always scared to trot and canter downhill so my horse ended up very front heavy. I guess she would always pull instead of push on the up and more than likely I had all my weight forward because I didn't know any better. But honestly, once you get the hang of trotting and cantering downhill, it's a great tool as well.
