I have never enjoyed balancing a low wing plane by putting the plane upside down on little sticks, yet if the plane is right side up it is to tippy when picked up at the wingtips. My last plane, I marked the fron and back edge of the balance pointe at the wingtips, and then attached a piece of tape at the tips with about 4 inches overhang. Then when balancing, lift by the ends of the tape. The tape allows the center of gravity to be below where it is liffted by the tape (which is precisely why a high wing plane is easy to balance).
