Best aftermarket sway bar?

[chevymotocross]

I'm looking to buy a sway bar for my 87 2wd silverado swb. It came with no sway bar from factory. Summit Racing sells sway bars from Belltech, Addco, and Hellwig. One brand better than the others? Any personal reviews?

Will these aftermarket sway bars bolt to my truck since it came with no factory sway bar? Or, must I also buy factory brackets to mount these?

Truck is at stock height now. I am eventually going to give it a mild suspension drop, but for now, I want some better cornering!
