OK guys,
I've added another variable into the mix.
I ordered the front Hotchkis bar to go along with my 14mm rear M sport bar.

Since Orb was kind enough to post about the different percentages, I'd like to add my setup to the mix.
I'm going to have the following:

Front
Hotchkis-31.75 mm: 75961 mm^4

Rear
M-sport-14.0 mm: 3771 mm^4

Front/Rear Biasing

Hotchkis front + M sport rear: 95% / 5%

I'll let you guys know about how this setup feels.
