I just installed a Load Warrior (With Extension).
Without the extension, it will work just fine.
With the extension you could still leave the front basket in (and not be able to remove it). However, you would only have about 5" to 8" between the Load Warrior and the wind deflector. Enough room to put small items. I just took my front basket out. I personally found it totally useless.
If you order a Load Warrior extension, it comes with a "Load Bar", which looks like it might be strong enough for a few lights. Or.. you can order the light brackets (for around 30 bucks).
Agee\'s Bikes sells Yakama products.. the are giving 20% on major purchases that you can use for smaller items like light brackets and nets. And they are also offering free shipping.
