I rode Phil pedals on my Masi with no problem back in the 70s. I have a banged up pair in my pedal drawer that gets pulled out from time-to-time when I need pedals for a quick around-the-block test ride on a build. As I understand it, the two problems with Phil pedals are the extrusion (pedal strike can easily crack them and/or badly scuff them) and that the axles can bend. ISTR (but can't find anything with a quick Google search) that when MKS was asked about bent axles on their pedals they replied that it was deemed safer than a broken axle, so they chose their steel alloy to bend, not break. (Maybe MKS should come out with a model named "Willow.") I assume that is/was true for Phil CHP pedals as well, though who knows if that was intentional or serendipitous.
