GL with the mediums, but perhaps you would do well with a different set of discs.
Its not the best picture but you can see I have the adjustment holes parallel to the reflex bend. It allows for some centering adjustment just not enough, I need 1 more hole that isn't there. It is there on the 2011s which allow for further adjustment.
To Burton do you have any reflex disks available that will allow more front/ back adjustment?
That would be my preferred solution.
