I have the Yakima LoadWarrior also. I got a good deal for the LoadWarrior+net at REI. $200 I think it's an exclusive package for REI.

Regarding the PlayPen's outriggers. to accomdate bicycle racks and other things along with my LoadWarrior, I just got longer WingBars. They were cheaper than the Isuzu bars. I also like that my bicycle sits abo0ut 6" lower than if I had the rack mounted on top of the basket instead of next to it.
