Another method might help, depending on your particular configuration. It has worked for me many times. Tie a second throwline to the weight that is sitting on the ground. Now pull the weight up into the tree and flip it over the little branch. You can now lower it slowly with the second line. If it will fall on the desired side of the big limb, you're golden. If not, you can position it just above the big limb and swing it back and forth with the first line in the plane that will carry it over the big limb. At the right moment let loose of both lines for a moment and the weight should fly over the big limb. You might need to add a bit of weight so it will come down of its own accord, since you will now have the friction of 2 lines to deal with. Hope this helps...
