Yes the MKS quills are quite lovely pedals.........but wait till you try threading on any pair of toe clip straps any thicker than a stick of gum..........
It will be a PITA..... The strap slots on the pedal body are just way too small.....
Haven't tried them but woven nylon straps might work better than leather ones on these as they are more flexible and can most likely go through the pedal body slots easier.....
