Yeah, not buying it. 1AM physics doesn't agree with it either. Crankshaft whip is a physical force, but the balance shaft is not physically connected to the crank. Now I think it may actually be an issue, but not because of crankshaft whip. The balance shafts can actually take out 2nd and 3rd phase harmonics which could resonate in the crank. When everything is balanced it will only minimize 1st phase vibrations.

That said, with all the engines out there with no balance shafts I don't think it can be that big of a deal.
