Gargoyle slider bumpers
I recently changed the soft slider bumpers into some harder plastic ones, because they got worn by frequent slider on/off changes: the original bumpers of my Gargoyle are really elastic, and they break in no time. I'm a little worried about friction that might occur between the lines of the canopy and the hard plastic at openings, because the plastic bumpers are much stiffer and the upper border much thicker and sharper.
Is line damage possible?
