When I bought the bow the draw length was set at 29"(this is my normal draw length)but there was no valley at all. I set it to 28" and it made it worse. By setting it to 30" I have a little valley now and a solid back wall, so there's no more adjustment to be made. I've been flinging some arrows in my backyard but Idon'tlike the feel of it at full draw, so I'll probably end up selling it.
