sway bar ? which one?

A friend and I took a ride to Summit and picked up a Hellwig bar.My friend,who has a addco bar was impressed,as was I with the quality of the hardware.The price was more than reasonable,140 bucks,plus I used my Summit bucks,so the bar ended up costing me 90 bucks.Can't wait to start wrenching after work tomorrow.It's supposed to get up to 50 by Thurs/Fri and be sunny,so I can wait to take it for a little ride.Between the bar and adding the shim to the power steering valve.I'm hoping to see a improvement in the handling and road feel.I'll let you know.
