Chris, I have the same issue with my AHH, which currently has 35mm Marathon Supremes and 45mm Honjo fenders. My tire rubs the fender when I pedal uphill standing up (swaying the bike from side to side). My assessment of this problem is that it is caused by wheel flex, not by the fender installation. I can actually see the front wheel flex as I sway the bike.
My AHH currently has Mavic Open Pro 32 spoked rims inherited from my pre-Rivendell days. I have to check out if the spoke tension needs to be adjusted and if the same issue remains if I use a Dyad 36 rim front wheel with the same tires. I'll have to do that soon, since I now have a couple of spare front wheels after getting SON 28 front wheels for the Atlantis and the Hunqapillar. If my assumption is correct, then your wheel would be flexing too and it might not be perfectly dished either.
