Harmonic Balancer Recommendations

I'm under the impression that SFI rated balancers are made to higher standards and have used Pioneer 872037 on my race car for years even though an SFI version is not required.
I don't have any experience with the other Pioneer balancers/dampers but have included them in the search for reference.

Attached is the correct image.
