Just to throw another kink into the discussion, I only re-adjusted the rear sway bar endlinks and left the front as they were, mainly because I didn't like the angle the front endlinks were going to be at. I "prefer" the endlink to sway bar angle be as close to perpendicular as possible.
The plates Jerry added mitigates this angular problem pretty well, from what I could see.
I've driven my 29M about 7-8 K miles since then and haven't had any ill effects from leaving it that way. Actually, I like it better now, for sure.
From suspension/engineering POV, stiffer Rear Sway bar should throw a little more weight on the front axle, and add just a little oversteer, maybe.

Given the $$ and opportunity, I will probably go with Sumo Springs all around first (Control the suspension travel during roll events), then work the Front Sway bar endlinks. After that, I will look at the Saf-T-Steer, then lastly the Track bar if needed.
As you can see, Personal Preference factors pretty highly in the realm of Steering and Suspension mods.
Just my 2 cents.
