Hi Bob,
I've only ever flown where it feels right. I have of course,with new models,tried options but I always end up at 32/33%.
Its the first thing I adjust, then work on the rest.
Maybe its time to rethink, but I think speed/style may have a role in this.
I may be wrong,as I have not yet tried, but I feel a forward CG will require more speed,
Also positive wing versus 0-0 debate is involved.
A few years back it was different as the entire schedule was from upright with only a little inverted work.
Now if any more inverted is added in we will have to put wheels on top as well. LOL
Take care Bob.

Brian
