I'm not exactly a "Hunter rider", but I definitely use my weight as a steering aid. Just sitting a little deeper on one seat bone versus the other, no leaning or anything. The weight aid works together with leg aids to guide and encourage the bend and hand aids to guide the shoulders.
Weight can be a really powerful, yet subtle aid. A simple adjustment of balance and weight distribution from the rider can result in a dramatic change in the horse's balance and the way he comes through a turn, for example.
Sally Swift has an excellent discussion on the use of weight aids and how to think of them in her Centered Riding book.
