so what is the best balancing method

As long as the wheel is straight and the tire is mounted correctly and has little to no runout, there's not a thing wrong with a good static (weights on one side or in the center) balance. Sometimes it is necessary to "turn" the tire on the wheel to get it to the best position and run true. normally, as long as the tire and wheel run nearly perfect on the balancer, you can get away with static.
