It seems as the majority of people recommend a welded lower single diagonal with the hard dog bar. But with a welded double diagonal, I believe the glovebox is still operable and there is less obstruction to the rear view mirror. So please explain the advantage of the single/why I would want to pick it?

From what I understand a single is required to meet SCCA specs and is a little bit stronger than the double.

Hmm...but not for HPDE events? Does everyone gradually get into driving SCCA events? I mean, I guess that would be an advantage though...

Really depends on your local club. Some allow double diagonal, but clubs that follow SCCA rules to the letter won't allow double diagonal as far as I know. That may even apply for HPDE; to even participate in a driving school in my club, convertible drivers need SCCA approved rollbars for insurance reasons.

I believe the single diagonal will generally interfere more with passenger seat clearances.

I have to ask the question that's been asked a million times I'm sure. Will the welded diagonal prevent use of the secret compartment?

Yes, a single diagonal bar will prevent the use of the secret compartment.

I never even notice my single diagonal in the rear view mirror.

With the welded diagonal and lower bar you will lose the compartment, but you'll get the most protection and proper harness height.

The double diagonal does not have a diagonal within the main hoop which I believe is necessary in order to pass inspections for racing organizations.
