I have read several times that the balanced that the balanced kits were very good and didn’t need anything, performed great, and lasted.
Those that have purchased kits have reported a good balance job but because there racing the scant few grams they were off was not good enough for them. I don’t ever remember the kits being reported as really bad. But the amount of perfection may not be what your after. You’ll never notice a s and dew grams out of balance. FWIW, factory balance jobs have been found Absolutely horrendous! And no one ever knew.
