RE: help on balancing low wing planes
It really only takes a couple of seconds to balance the plane level. Then we know exactly where the CG is 'from the LE of the wing' or wherever the mfg suggested.
If you want a slightly nose heavy airplane then have it balance ahead of the recommended distance. Fly it and decide if your extra distance worked for you. The mfg's suggestion usually is very much on the safe side anyway. They fly a lot better when they are better balanced. And you'll know accurately where the balance is that worked for you.
