I only run main girdles. I use custom pans/baffles to keep the oil where it belongs.
I don't run nitros so hypers have always worked fine for me. I ran forged a few times but I dont like them on the street.

Breakin isn't much of an issue if you're running a hydraulic roller cam. Do you have any pics of your custom oil pans with the baffles inside? I'm thinking about doing the same on my new engine.
As for the balancing issue, you'll probably find that 28 oz.-in. imbalance will be the closest to most crank/rod/piston combo's. Exceptions may be in situations where you have a really light piston/rod combination, combined with a heavy (forged) crank. Neutral balance will cost a fair bit more, as mallory slugs are pretty darn expensive. Yes, the flywheel and balancer both have to have the same imbalance. I do agree a lot with Andy669's post...where the weight is matters a lot, so neutral balance would be the best if you can afford it. Having the weight closer to the center of gravity will make it easier to spin.
