The answer to your question would depend on: how far from your axis you want the pin, how far from the VAL you place the pin, the actual pin distance on the ball, and the cg placement on the ball(right or left of a line between the pin and mb.
Generally the lower the better, to avoid having a large weight hole in the finger positive quadrant.
If you want to look at one without a weight hole, I have a 15#TNV for sale right now on eBay with a modified TJ layout (pin 5"from axis, 1.5" from VAL)
Hope this helps
