Another thing. Jaco will no doubt be aware of the criticism and the suggestion that he's not neutral. Wouldn't that be a good motivation for him to try to be as neutral & good as he can be this Saturday? Unless he's really biased, of course. I have more of an issue with vdW and Jonker, although they are still better than van Heerden and Veld (remember that Blues game in SA).
Having said that, I find it incomprehensible that they use the argument that Jackson was the ref last year in Wellington to justify the appointment of Peyper. Two wrongs don't make things right. You should always go for the most neutral ref if there is a good & suitable one available, in this case Gardner.
Anyway, I think the travel factor & altitude will be a more important reason for a possible Crusaders' loss, than the refs.
