Thanks everybody. I would like to have it mounted to a front rack (I would actually rather just have a front rack) but I don't have one so I need to use the included mounting arms.

I wasn't considering mounting it directly to the quick release skewer since the instructions from wald's site explicitly said not to do that. Are some of you running it like that, without the additional front rack for support? Have you had any problems? How much weight have you had in it with the setup like that?
