From my Sapphire days, I had a solid steel wingrod I used for ballast, it added 16oz, and that was my start point. I would probably wait till 12-14mph of wind. Remember, that when ballasting, you need to make a significant difference in loading on an airfoil like the 7037. Your 5 and 8oz bars, I am guessing you will not even notice the difference, but the 14 and 22oz bars will be useful. Your install is very nice.

The new airfoils, and current very light airframes, ballasting has changed a bit since those days and when we flew 7037's alot.
