I'm thinking vband will cut that problem and make removal 100 times easier in the future.
Thoughts?

I really like the idea of the V band, especially since you've had a few issues on that side. But from a QA perspective, it sounds to me like your mating surfaces are warped slightly, and not matching or exerting even pressure on the gasket, which is why there have been multiple problems in the same place. Converting it to allow for "pipe docking" as BettyZ describes it so perfectly might solve the issue for good.
